1. Sheldon Cooper

Sheldon Cooper is one of the “nerds” on the show who’s portrayed with a high IQ and few social skills. He represents, it’s fair to say, what many might think of the average, pencil-pushing scientist. While the existence of people like Neil deGrasse Tyson makes this perception unlikely to be true of some scientists, we can assume it’s true of at least a few.

sheldon writes math on a white boardsheldon writes math on a white board

In the show, he’s awkward, full of weird quirks, and likely to remonstrate against anyone who takes an anti-scientific point of view. He even dresses nerdily, often vaunting the short-sleeve-shirt-over-long-sleeve-shirt with poorly matching slacks. And beyond that, his short sleeve shirts often brandish scientific concepts like DNA. He is, in other words, a card-carrying nerd.

2. The real Sheldon Cooper

The real Sheldon Cooper goes by the name of Jim Parsons. Parsons is, in contrast to his portrayal in The Big Bang Theory, much more affiliative and charismatic. Originally from Houston, Texas, he now lives in Los Angeles with his partner, Todd Spiewak.

While it’s fair to say that the majority of Parsons’ fame is derived from The Big Bang Theory, he has been involved in numerous other films and television shows. These include Hidden Figures, A Kid Like Jake, and Young Sheldon—a spinoff of the already popular show. His roster and breadth of work show that Parsons is likely more gregarious and adept than his persona in The Big Bang Theory would have you believe.

3. Leonard Hofstadter

Leonard Hofstadter is a slightly more affable scientist than Sheldon Cooper. Ostensibly less subject to the scientific stereotype, Hofstadter has a girlfriend (who would later become his wife), a friendly demeanor, and a breed of jest that implies he understands social situations to a degree that most normal people would sympathize with.

Unlike Sheldon, he doesn’t get angry about mockingbirds being out of tune with wind chimes or spoil major plot points in Harry Potter novels. Either way, he is a breath of fresh air in The Big Bang Theory‘s world of scientists, offering balance to the awkwardness of other characters. But what is he like in real life?

4. The real Leonard Hofstadter

The real Leonard Hofstadter is Johnny Galecki. Galecki appears as a debonair and well-put-together man, first having made his career as David on Roseanne. But beyond this, he has gone on to star in a sequel to The Ring (entitled Rings) and a comedy follow-up to Roseanne called The Conners.

Originally born in Belgium, Galecki grew up in Chicago and began his involvement with the acting community around the age of seven. This beginning started with theatre, eventually bringing him into minor (and then not-so-minor) roles in movies and sitcoms. Eventually, the experience would bring him to The Big Bang Theory.

5. Rajesh Koothrappali

Rajesh Koothrappali suffers a unique dilemma in The Big Bang Theory: He is not only the owner of a formidable pair of sideburns, he is also the character who experiences too little of that thing we would all like more of: love. While this may be a plight of some astrophysicists, it seems to be impressively true of Koothrappali.

At one point in the show’s tenure, Raj had to down a drink in order to even approach a woman. The unfortunate disposition brought him much malaise, yet us, the audience, much schadenfreude and joy. In real life, however, Raj is a far different (and far less inept) person.

6. The real Rajesh Koothrappali

Raj Koothrappali is played by none other than Kunal Nayyer. Having been born in London, he comes fully equipped with a dashing accent and personality that sharply juxtaposes the awkward and weirdly dressed character he plays in The Big Bang TheoryInterestingly, The Big Bang Theory was Nayyer’s first major exposure to the world of TV acting, and one that would last.

Unlike his persona on the screen, Nayyer is happily married—and to the fashion designer Neha Kapur Nayyer at that. But beyond his relationship status is an affinity for a pastime you wouldn’t expect of the astrophysicist he plays on-screen: golf.

7. Mrs. Koothrappali

Mrs. Koothrappali is Raj’s mother. Somehow, she has never managed to show up on-screen other than on the literal screen; we’ve only seen her on the computer. This diminutive role has often been employed for temporary comedic relief (from an already comedic show).

mother and father on the screenmother and father on the screen

The mother offers many roles, including that of disparaging Penny as an unsuitable mate for her lack of Indian heritage. But other than that, she and her husband love to pester Raj incessantly to find a wife and have children. Ultimately, she is full of fun idiosyncrasies that make her seem unfamiliar with the norms and culture endemic to the United States life.

8. The real Mrs. Koothrappali

Mrs. Koothrappali is played by the actress Alice Amter. Amter is a British actress who has been living in the United States for around 20 years. While her role as Mrs. Koothrappali was supposed to be a one-off, fans of the show found her performance and character compelling enough to keep her on.

two people on the red carpettwo people on the red carpet

The 52-year-old has also acted in many other shows, series, and movies, including The Book of Daniel, A Man Apart, and Hot in Cleveland. While her acting career is diverse and expansive, we probably all (as avid fans) know her most affectionately from her endearing performances in The Big Bang Theory. We look forward to her future work.

9. Priya Koothrappali

Priya Koothrappali is another of Raj’s relatives—and a formidable one at that. She is a lawyer and the only other plausible contender—according to Penny—for the role of Leonard’s girlfriend. Unfortunately, her success as a lawyer and potential girlfriend made her the bane of Penny’s existence for Season 4.

two people in a kitchen while in their robestwo people in a kitchen while in their robes

Because of this, she was considered the main antagonist of the season. Regardless of the antagonism between Priya and Penny, Priya manages to sleep with Leonard on a few occasions. Their relationship, however, is not enough for her to accept Leonard’s supplications to move with her to India. She thinks their relationship isn’t serious, and not worthy of a move far east.

10. The real Priya Koothrappali

The real Priya Koothrappali is played by Aarti Mann. Having studied at New York University’s theatre department, Mann appeared in a film of her sister’s, The Memsahib, and as a character in the popular show Heroes. Originally born in Connecticut, Mann has since relocated to Los Angeles, CA.

Like Raj’s mother, Mann was originally brought on board to serve a smaller role. But again, like with Raj’s mother, fans of the show liked her so much that the screenwriters decided to give her a more prominent role. And with that, Priya Koothrappali was born. While in real life she is not as involved in law, she shares many similarly formidable traits.

11. Howard Wolowitz

Howard Wolowitz is a character that never outgrew the ’60s Beatles haircut. With the sideburns and musical talent to match, Howard is an engineer who is often denigrated as such. In case you were unaware, engineers are often derided (as a joke, of course) by scientists for their non-experimental training.

nerdy guy in tarrible clothingnerdy guy in tarrible clothing

Wolowitz isn’t one of the show’s stars, like Raj, who’s aggressively in pursuit of love in recent seasons. Instead, he has found it in the form of Bernadette. He’s made the woman his wife, despite her status safely beyond his league. The pair have two kids together, who they raise in all the engineering glory of the Wolowitz household.

12. The real Howard Wolowitz

Howard Wolowitz is played by the imitable Simon Helberg. Decidedly more put together than his on-screen persona, Helberg is married to a fellow actress, Jocelyn Towne, and engaged in his own array of acting pursuits. These include such notable numbers as Old School, A Cinderella Story, and We’ll Never Forget Paris.

But other than his lengthy filmography, he is also involved in other creative pursuits. He is a musician and comedian, for instance. But for The Big Bang Theory more specifically, Helberg has earned a coveted Critics’ Choice Television Award for Best Supporting Actor in a Comedy Series. We’d be curious to see how well the other aspects of his career are doing.

13. Amy Farrah Fowler

The only person with a comparably awkward persona to Sheldon Cooper is Amy Farrah Fowler. Having earned herself the awkward role of Sheldon’s online dating partner, the neurobiologist seems an appropriate match for one of the more peculiar characters in the series.

a woman in a purple jacketa woman in a purple jacket

Because of their fitting merits, the two got married during the 11th season. It seemed only appropriate that two of the most bizarre characters get wed in a marriage of two bizarre people. Her character, unlike all of Raj’s family, was written into a more prominent recurring role. Clearly, her character was important enough to make a frequent regular.

14. The real Amy Farrah Fowler

The real Amy Farrah Fowler is played by Mayim Bialik. Much to her credit, Mayim Bialik has something that distinguishes her from the rest of the cast of The Big Bang Theory: an actual PhD in an actual scientific field. Bialik earned her degree in neuroscience from UCLA, a formidable institution for the neurosciences.

woman in a black dress in an interviewwoman in a black dress in an interview

In her free time, she writes. Her books cover everything from veganism to different styles of parenting (the focus of her PhD). So, contrary to the other cast members, Bialik is an actual scientist. While she took her career in the direction of acting instead of academic science, she still has the credentials to maintain both. 

15. Bernadette Rostenkowski-Wolowitz

Bernadette Rostenkowski-Wolowitz is a microbiologist with a bullying tendency to push other people into doing what she wants. She got married to Wolowitz in the finale of Season 5, solidifying their quirky relationship for time immemorial. It was only appropriate, given the pair’s quixotic and peculiar relationship.

But other than the marriage, Bernadette had humble origins, having similarly been a waitress at The Cheesecake Factory. Later in the show, she and Howard have two children together in quick succession. The two live together in her apartment in Pasadena. They live happily ever after with their two children throughout the show.

16. The real Bernadette Rostenkowski-Wolowitz

Bernadette Rostenkowski-Wolowitz is played by Melissa Rauch. Interestingly, her pregnancy in the show was spurred by her actual pregnancy in real life. Given that the show did not want to (and in fact could not) conspicuously write her out of the show, they had to adapt to her shifting abdomen.

a woman and man on stage with a blue curtain behind thema woman and man on stage with a blue curtain behind them

And what better way than to make her pregnant. In the rest of her acting career, Rauch has played everything from an ex-Olympic gymnast to Harley Quinn. Her portfolio will likely only grow as she continues to flourish in her legitimately non-nerdy way. We look forward to her growth in her acting career.

17. Penny

Penny, one of the main protagonists of the show, is one of the only characters uninvolved with the scientific community. She is not an academic, she is not particularly well-informed on scientific matters, and she illustrates many faux pas that the scientific community might balk at.

a woman looks agast as someone nearby says something totally shockinga woman looks agast as someone nearby says something totally shocking

She is an aspiring actress, a former employee of the prestigious Cheesecake Factory, and portrayed as what many might describe as the “dumb blonde.” Much to her credit, she is not written to be as dumb as superficial appearances and untoward stereotypes might suggest. Either way, her character is meant to mimic how the scientifically uninformed audience might think.

18. The real Penny

Penny is played by the actress Kaley Cuoco. Amazingly, after several consecutive seasons of the show, Cuoco has risen to such a starring figure that she is now one of the highest-paid actresses on TV. For the most recent seasons, she has earned around one million dollars per episode.

woman with short hari making a facewoman with short hari making a face

But Cuoco has other talents than what she shows on-screen. She is also a talented tennis player and die-hard equestrian. While her love for the latter did bring her to get engaged to a professional equestrian, she has since realigned her relationship status to Karl Cook, her costar on the show. Their romance went from on-screen to off.

19. Stuart Bloom

Stuart Bloom is the owner of a comic book shop. Described as a lovable loser, the man spends his time babysitting Bernadette’s kids and managing his shop. Fortunately for him, Neil Gaiman, the famed science fiction writer, tweeted about his shop. The privilege gave his store ample business.

a man staring blankly in an elevatora man staring blankly in an elevator

But other than the business and babysitting, Stuart has also been a caretaker for Howard’s mother. The man is both part nerd and part caring man. Because of this, the show and its audience adore him. Does this favorable portrayal represent the real-life Stuart Bloom? The answer is probably what you expected…

20. The real Stuart Bloom

Stuart Bloom is played by Kevin Sussman. Sussman has starred in many other shows, including Ugly Betty, and movies. Sussman has appeared in a handful of feature films, including Hitch, Sweet Home Alabama, and Wet Hot American Summer. But other than his roles in film and TV, Sussman also counts himself among comedians.

a man smiling into a microphonea man smiling into a microphone

The variegated career trajectory of Sussman is only expected to grow as he gains more prominent roles in more movies. We look forward to his growth as an actor and comedian with the additional roles he plays after the dissolution of The Big Bang Theory. We’re sure he will surprise us with his new, and presumably just as fun-loving, characters.

21. Mary Cooper

Mary Cooper is a far step from her son, Sheldon (i.e., Shelly). And how, you might ask, is she different? Well, if you’ve made it this far, you likely already know the answer: she is fervently religious. Hailing from the Bible Belt, she holds strong opinions on things like scientifically unsupported “home remedies” and the like.

a woman lecturing another womana woman lecturing another woman

This is, as we would say, diametrically opposed to the scientifically captivated Sheldon. Their relationship shows that oftentimes a scientist will come from a world of parents that are not so, in and of themselves, scientific. Yet still, the inner scientist in the person can flourish, as we see clearly happening with our little Shelly. 

22. The real Mary Cooper

The real Mary Cooper is played by Laurie Metcalf. Mary Cooper is a distinguished Academy Award-nominee for her role in Lady Bird. But other than that, she has also played a prominent role in the show Roseanne. She has even recently played a role as Hillary Clinton.

a woman holding a grammy at a partya woman holding a grammy at a party

Her diverse roles have earned her much prestige in Hollywood. While her fame from her Roseanne days will likely outshine her brief and mildly diminutive role in The Big Bang Theory, she will still be heralded as a great addition to the show. Her legacy will live on as one of the few people to coax Sheldon into a handful of unscientific things.

23. Dr. Beverly Hofstadter

Dr. Beverly Hofstadter is the mother of none other than Leonard. She is a neuroscientist and psychiatrist who likes to maintain her distance. Stereotypes abound in the world of The Big Bang Theory, and Leonard’s mother Beverly is no exception. She portrays the cold and calculating scientist mother.

woman looking quizically at someone elsewoman looking quizically at someone else

While the likelihood of this mother’s existence is likely less prevalent than this stereotype would have you believe, people like Beverly surely exist. But is she as cold and distant as you might be led to believe from The Big Bang Theory? This question doesn’t take more than a brief look at her personal life to unseat that reputation.

24. The real Beverly Hofstadter

The real Beverly Hofstadter is played by Christine Baranski. Baranski has been in the media for a long time, playing roles in movies like Chicago, Mamma Mia!, Into the Woods, and The Birdcage. Each of these movies has helped to solidify her position in the Hollywood elite. It wouldn’t take much for her to get another role.

a woman in a dress at a party doing somethinga woman in a dress at a party doing something

But despite her role in The Big Bang Theory, she is not as cold and distant as her academic persona would have you believe. Instead, she is seen as warm, affable, and gregarious. If you’d like earn a long-time tenured position in the Hollywood scene, you might want to take note of Christine Baranski’s career.

25. Barry Kripke

Barry Kripke is a more subtle character in The Big Bang Theory. He is a string theorist at Caltech, one of the most premier science and technology institutions in the world. It is especially known for physics, so you can expect that this guy’s reputation precedes him.

man holding a yellow folderman holding a yellow folder

In the show, he plays a mild antagonist, playing tricks and attempting to bamboozle Sheldon. Fortunately, he does not have too great a success rate. Because of this, the banter will remain light and jovial between the two, likely inspiring future camaraderie and jest. But in real life, his character is far less nerdy.

26. The real Barry Kripke

Barry Kripke is played by John Ross Bowie. Not related to the star of Ziggy Stardust fame, Bowie is an actor who’s been involved in many acting projects. He’s currently working on another show with fellow The Big Bang Theory star Kevin Sussman. The show is set to be a hoot.

john ross bowie on stage with beardjohn ross bowie on stage with beard

But other than this endeavor, Bowie has engaged with numerous other scripts and projects. Among these include roles in Speechless, Death in Paradise, The Heat, and the simply named Love. These TV shows have helped to steadily nourish Bowie’s career as an actor. And for this, we are infinitely grateful. He is, after all, one of the few people we enjoy watching put Sheldon in his place.

NEXT: The darkest secrets behind the “Big Bang Theory” revealed in wake of final season

1. Strike one

At the very beginning of the show, the Writer’s Guild of America went on strike against the Alliance of Motion Picture and Television Producers following a labor dispute. The protest lasted for four months, halting production of the show. The Big Bang Theory had only aired eight episodes when the strike started.


From November 2007 to February 2008, while the Writer’s Guild of America was on strike, those eight episodes were reaired three times. In spite of four months of reruns, the show’s ratings held steady. When the strike ended, the writers released nine more episodes over the next two months in an effort to catch up to the required creative output.

2. Holding steady

In spite of the labor strike that cast a shadow over roughly half of the show’s first season, The Big Bang Theory held strong. The fact that people stayed interested through four months of reruns proved to the producers that their show could stand on its own from the start.

TV Insider

Some even speculated that the show’s potentially-dooming rerun stint helped them out in the long run. CBS saw that The Big Bang Theory‘s success wasn’t a fluke. The strike did cause the first season to be cut short, airing a few episodes shy of the initial plan, but the promise of future success ultimately drove the funding for more content.

3. An unsavory theme

A type of issue that The Big Bang Theory faced on multiple occasions was lawsuits. Over the past decade, the show’s representatives have seen their fair share of time in the courtroom, and not just for the on-stage activities. One of those legal misadventures was fought in the name of royalties from the show’s theme song.


The intro to the show is a rapid-fire rundown of the history of evolution from the beginning of the universe to where we are now. The song that plays was initially performed by the Barenaked Ladies, whose frontman originally performed the song as a freestyle rap skit during one of their concerts.

4. IOU

Ed Robertson, the Barenaked Ladies frontman, met with The Big Bang Theory producers Chuck Lorre and Bill Prady. They asked him to come up with an intro for their show, and Robertson supposedly created the demo for the song in a single morning. The band recorded the final product and handed it over.

Facebook — Barenaked Ladies

In 2009, one of the members of the Barenaked Ladies, Stephen Page, left the group. In spite of having been part of the band when the show’s theme tune was recorded, he claims to have never received royalties, and he filed a lawsuit in 2015 to dispute it. The case remains unresolved.

5. Soft kitty

The Big Bang Theory‘s theme song isn’t the only musical element in the hit TV show to cause a legal fuss. Audiences loved certain scenes where Penny must comfort an ailing Sheldon by singing a calming song. The tune itself, Soft Kitty, created its own uproar after a family stepped forward to claim rights to the favorite song in the wake of its monumental success.

Entertainment Weekly

Ellen Newlin Chase and Margaret Chase Perry filed the lawsuit, claiming that the song had been written by their mother, Edith Newlin, as part of a compilation of children’s songs. Based on their relation to the creator of the song, the sisters claimed they deserved royalties for the song by default.

6. No luck

Although their mother had, in fact, held the copyright for the song Soft Kitty, she had registered the collection of songs with Willis Music. When the producers sought permission to use the song in The Big Bang Theory, they negotiated solely with Willis Music and not with Newlin’s daughters.

The Wrap

Following Newlin’s death, her copyright passed on to her daughters, leading to their accusation that they were owed an amount in royalties. However, when the company renewed the copyright on the song collection, it did not renew the daughters’ copyright, leaving Willis Music as the only legal owner of the songs.

7. What a rip-off

Fortunately, not all of the lawsuits surrounding The Big Bang Theory have been aimed at them. They say imitation is the best form of flattery, but in one instance, the producers of the show accused another set of producers of making trouble when they discovered a nearly direct rip-off of the show airing overseas under the title The Theorists.


The imposter show, which was discovered in 2010, featured a main cast of characters named Sheldon, Leo, Hovard, Raj, and Natasha. The first four made up a group of nerdy scientists trying to get by in the real world alongside their attractive across-the-hall neighbor who worked as a waitress. It would seem blatantly obvious that other stations were trying to cash in on the coattails of TBBT.

8. We’re out

The copycat show was based out of Belarus, and each episode was a direct translation of that episode’s Big Bang Theory script into Russian. The original show’s producers weren’t certain how they were going to tackle the issue given that it was airing in a foreign country. Legal discrepancies get tricky across national borders.

Great, Fantastic, and Good

Normally, they would have sued for copyright infringement, but the production company behind The Theorists was owned and run by the Belarusan government, putting the American showrunners in a bit of a predicament. Fortunately, once the actors in the imposter show heard they were acting in a rip-off, they quit.

9. Drawing heat

Lawsuits aren’t the only burden that has plagued the show and its creators. An ongoing source upset surrounds the main character’s portrayal. Many people have complained that Sheldon’s eccentric personality seems less like a funny character trait and more like a thinly-veiled jab at individuals with Asperger’s Syndrome.

TV Guide

For those who might not be familiar, Asperger’s Syndrome is a developmental disorder that affects an individual’s social skills. It is part of the autism spectrum and is typically characterized by obsessive compulsion, social awkwardness, and an all-absorbing interest in specific topics. As with any disorder, it’s not something you poke fun at.

10. Not us

When you look at Sheldon, a surprising number of his personality traits match up with those of someone with Asperger’s Syndrome. In particular, his tendencies toward inappropriate social interaction, difficulties with nonverbal communication, and his inability to understand social and emotional issues stick out. As a result, the writers have drawn some fire.

Hollywood Reporter

Complaining viewers say that they can’t tell if his character is meant to be a mockery or a representation of someone on the autism spectrum. The show’s producers and writers have denied the existence of an intentional link, though after some research, they have admitted that the similarities are there.

11. Salary wars

Over the past ten years, several disputes have turned up over actors’ salaries, and The Big Bang Theory was no exception to that circuit. More than once, the lead actors in the show confronted their producers about the cast’s wages. In 2013, the first negotiation arose among the main cast.

Pinterest — JoyMarie Burrell

Jim Parsons, Kaley Cuoco, and Johnny Galecki all banded together to negotiate salary increases for each of them in light of the show’s success and ever-increasing popularity. Their negotiations halted production for a short time until the actors received a raise. That wouldn’t nearly be the end of wage discussions, as each actor felt their valuation should be substantially higher.

12. We want more

After the show’s three leads negotiated a raise in their salary from $350,000 an episode to a whopping $1 million a pop, the other two stars of the show, Simon Helberg and Kunal Nayyar, finalized their salary hikes from $100,000 to $750,000 per episode. They had initially tried for $1 million price tags, but to no avail.

The Tribune

The studio told Helberg and Nayyar that they could have $750,000, take it or leave it, and the actors were forced to settle. Four years later in 2017, the five stars agreed to a $100,000 pay cut off of their one million each so that their costars, Melissa Rauch and Mayim Bialik, could each make $425,000 per episode.

13. Dark origins

Going back to the very beginning of the show, The Big Bang Theory started out on a very different note. Initially, the show pitched itself to CBS with a very dark pilot that never made its way to the public side of the network. The 2006 version of the show was turned down.


The network asked the producers to try again and come back the following year with a different pitch for the show. The 2007 version of their pilot was what ultimately made the cut and established the cast and chemistry of the show as we know it. Its predecessor was far more depressing.

14. A messy situation

In the original pilot, Leonard and Sheldon were the only two recognizable characters, though they deviated drastically from their final iterations. Sheldon was noticeably different, appearing as a girl-crazed fiend caught in the middle of a weird love triangle. The supporting cast also saw a lot of changes between versions.

Too Fab

Penny’s predecessor was named Katie. Katie lived with Sheldon and Leonard because her married boyfriend had kicked her out. She had a taste for hard liquor and was far more cynical than Penny. In place of Howard and Raj, the two guys had a single female friend, Gilda, who liked Leonard and had a romantic history with Sheldon.

15. Same coin

Just like many authors create characters based off of themselves, some actors and actresses play roles that are reflective of their personalities. A good example is Aubrey Plaza in her role as April Ludgate in Parks And Recreation. However, this isn’t always the case, and sometimes, it can be quite the opposite.


Jim Parsons, the actor who plays Sheldon Cooper, couldn’t be more different from the character he portrays on screen. From their interests to their study habits, Sheldon and Jim not only disagree, but they likely wouldn’t get along well if they were to meet as people in real life.

16. Two sides

Sheldon is an avid Star Trek fan, and his love for the classic TV series has played an integral part of his character progression. He and his friends have had an episode where they were on their way to a Star Trek convention, and several other episodes have featured cameos from Trekkie cast members.


Despite working on set alongside Wil Wheaton, George Takei, Leonard Nimoy, and Brent Spiner, Jim Parsons has never seen a single episode of any era of Star Trek. In another diversion from his character, Parsons has also never seen an episode of Doctor Who. Based on interviews, we also know Parsons is not nearly the bookish type Sheldon is.

17. Awkward moments

The Big Bang Theory is an undeniably nerdy show, and it’s no stranger to social awkwardness. The cast and crew have had their fair share of awkward moments and explanations. Some of the guest stars to their stage have been cast in somewhat unusual roles, at least when compared to their original characters.

Science Fiction

One of those instances surrounded the casting of Wil Wheaton as the antagonist of one episode. The show’s executive producer, Bill Prady, was left in charge of calling Wheaton and pitching the idea: “I had to call him and say, ‘So you’re playing yourself …but you’re a real d**k!'” Fortunately, Wheaton was all for it.

18. Oh myyy

In another episode, Howard experiences a vivid fantasy featuring two of his sci-fi heroes. The showrunners called in Katee Sackhoff and George Takei in for the scene and found themselves faced with an awkward situation. Someone had to explain everything to the guest stars, and the responsibility once again fell to Prady.

E Online

He explained the scene as such: “We wrote a line of Howard saying, ‘I’m so confused,’ and thought it’d be really funny if George Takei said, ‘Confused? Perhaps I can help.'” When it came to explaining the idea to Takei, Prady eventually settled on the line, “So you know you’re gay, right?!” Takei responded, “That’s news I’ll tell my husband!”

19. Rough acting

For many of the actors, what you see on the screen hides a plethora of real-world drama and issues from viewers’ eyes. From injuries to relationships, what reaches us is only a small portion of the truth. To learn more, you have to go behind the scenes to find out what’s up.

Hobby Consolas

Kevin Sussman, the actor who plays Stuart on the show, is a prime example of this phenomenon. Sussman has intense anxiety about being underwater. At one point in the episode “The Hot Tub Contamination,” Stuart emerges from underwater in a hot tub. Getting that shot was a surprising amount of work.

20. Going in deep

Sussman’s phobia of water was specifically surrounding the concept of putting his head beneath the surface. According to the actor, it wasn’t something that he ever did. To work around and with his fear, the production crew made sure he felt safe throughout the entire scene by providing constant support.

The Spectrum

In the actor’s own words, he said, “I don’t like putting my head underwater ever… a bunch of people had to coach me, you know, ‘it’s going to be okay, we have a lot of people around.’” Thanks to the support of those around him, he was able to complete the scene.

21. Breaking in

Psychological hurdles weren’t the only setbacks for some cast members. As expected, throughout the decade, there were some injuries sustained by various cast members. Some producers choose to write the injuries in, but the showrunners for The Big Bang Theory took a slightly different approach and shifted the scenes a bit instead.


The first incident occurred in 2010 when Kaley Cuoco sustained a severe leg injury while horseback riding. She spent the two weeks following the event in the hospital, during which time she was written out of the script. When she returned, the directors hid her broken leg behind a bar instead of writing it in.

22. Accidents happen

Cuoco wasn’t the only cast member to sustain an injury during the filming of the show. Two years later, co-actress Mayim Bialik faced a similar issue after breaking her hand in a car accident. While Bialik’s injury didn’t cause her to miss filming as Cuoco’s had, it still posed a problem for the directors.

Rumor Fix

The showrunners once again opted not to write the injury into the story. Instead, they changed the filming and staging angles ever so slightly so at no point was Bialik’s injured hand facing the camera. Fortunately, camera and lighting trickery can go a long way to hide visible ailments. However, not all on-stage adaptations were quite so successful.

23. Heard but not seen

Intentionally manipulating what the audience can and can’t see of the cast and characters is something that the producers did for more than just injuries, and it’s a common practice with many sitcoms. Throughout the show, we hear characters off-screen that we rarely, if ever, get to see. One of these unseen characters is baby Halley Wolowitz.


During season 10, the focal point of the show’s drama surrounds the expectant birth of Howard and Bernadette’s daughter, Halley. In spite of all the excitement that permeated the entire season, we never actually get to see their baby. Instead, we only hear her cries from other rooms off-screen. Again, this isn’t an uncommon technique in the film and TV biz, but the decision was still met with some controversy.

24. A touching tribute

Part of the decision to keep Halley Wolowitz as an off-screen entity was to avoid the complications of having an actual baby on set. The deeper and more touching reason the directors have created Halley as a purely audio role is that her existence pays tribute to a late actor from the show.


Back in 2014, Carol Ann Susi, who played the voice of Howard’s mother, passed away. She was another character who never made an appearance on-screen, but her grating shouts could often be heard in another room. Baby Halley’s audio-only role pays homage to Susi’s role in the show.

25. It’s not all bad

While being an actor may not always be the most pleasant or comfortable job, not every instance of grin-and-bear-it is quite as gruesome as the last. Injuries, personal hurdles, and accidents happen, but most of the discomfort on set stemmed from uncomfortable wardrobe choices made by the showrunners.

Reggie’s Take

Two actors, in particular, seemed to find themselves always at odds with their clothes. Kunal Nayyar envied Kaley Cuoco’s comfy wardrobe of tank tops and shorts. Raj’s dress sense erred on the side of being too hot with sweaters and layered clothes. The actor also spent 20 minutes every day straightening his naturally-curly hair for the show.

26. Sucking it in

Of all the costuming and day-to-day woes on the set, most members of the cast agree that Simon Helberg may have had it the worst. His wardrobe isn’t hot like Nayyar’s, but it is still uncomfortable. Howard’s signature look features a pair of skinny jeans and one of his many wild belt buckles.

Helberg’s regular wardrobe is far less extreme. His commentary on adjusting to his on-screen garb is, “I’ve learned the smallest pants size I can squeeze into!” The actor says that, of Howard’s belt buckles, his favorites are the ones that don’t stab him when he sits down.

27. Scripted love

Ten years is a long time. For many of us, ten years have marked the transition from one stage of life to another. During that time, most of us have experienced significant changes in the love department: Dating, marriage, families, the works. The same can be said about these characters.

The Indian Express

The cast of The Big Bang Theory has had their fair share of changes alongside their characters. Most notably, as Leonard and Penny developed an on-screen relationship, Kaley Cuoco and Johnny Galecki nurtured a budding romance of their own. However, the love between Cuoco and Galecki ended up being far less sweet than its on-screen counterpart.

28. Bittersweet developments

The real-life romance between Kaley Cuoco and Johnny Galecki lasted about two years and was conducted in secret so as not to detract from the budding relationship between their on-screen personas. The two of them denied their relationship in public and never told anyone about it until after the fact.


When asked about their relationship, Cuoco said, “It was such a huge part of my life and no one knew about it. It was a wonderful relationship, but we never spoke a word about it and never went anywhere together.” She believes that the secrecy ultimately led to their breakup, though the two remain good friends.

29. Based on a true story

One of the coolest and least-known facts about The Big Bang Theory is that it is mostly based on real-life scenarios, people, and quirks. While no continuous element of the story is based on a real-life event, the producers and the cast explain that there’s a lot of external influence.

Executive producer Bill Prady explained that Howard Wolowitz’s character was inspired by a former colleague of his by the same name. He also stated that some elements of Sheldon’s personality were drawn from his interactions with computer programmers during the short time where that was his field of study. The various traits of other characters are an amalgamation of some of the writer’s personal experiences as well.

30. A labor of love

Even some of the conflicts on the show were inspired by interactions between the actors and their spouses. One example is Penny’s inability to remember Leonard Hofstadter’s birthdate, even after they get married. Writer Jeremy Howe claims he drew inspiration for that conflict from his wife, who can never recall his birthday.


Some of the wildest stories are based at least partially in truth, and The Big Bang Theory is no exception. We can expect to see more goofiness, drama, and character growth for two more seasons. The show is planned to end after its 12th season in 2019, but until then, we can sit back and enjoy.
