The Big Bang Theory has been making audiences laugh since its premiere in 2007, when we were first introduced to the geeky but brilliant crew of CalTech researchers and their neighbor, Penny. After 10 years on the air, here’s what the cast looked like then and now.
Simon Helberg as Howard Wolowitz – Then
Though often looked down upon by Sheldon because he ‘only’ holds a Master’s degree in engineering from MIT, Howard eventually manages to parlay his expertise into becoming an astronaut for NASA. In the early seasons, Howard was often trying and failing to score a date with a variety of different women, That all changed with Penny introduces him to her coworker Bernadette in season 3, who was working at the Cheesecake Factory in order to pay for grad school.

Simon is another one of the original cast who has been with The Big Bang Theory since day one, when he was introduced as the nerdy mama’s boy, still caught under his overbearing mother’s thumb. Recently, Simon has also managed to fit in several film appearances in addition to his work on The Big Bang Theory, including a turn as the pianist Cosme McMoon in Florence Foster Jenkins, which also starred Meryl Streep and Hugh Grant.
Laura Spencer as Emily Sweeney – Then
Laura Spencer plays the slightly morbid dermatologist that Raj meets via online dating during the seventh season of the show. She becomes entangled in a love triangle with Raj and another woman he’s dating, Lucy, but Emily is unfazed. The two enjoy watching horror movies together, and she entertains Raj with macabre jokes. They eventually enter into a fairly serious relationship, but Raj finds in the end that he is still struggling with commitment.

Raj wasn’t the only one two timing, as Laura Spencer was also appearing in Bones as Jessica Warren, which recently wrapped production. While it’s unclear whether or not Laura will reprise her role as Emily in the near future, as Raj recently broke up with her again, she doesn’t seem to have ruled out the possibility. In the meantime, Laura recently filmed a short film called Vitality, where she plays the role of Christine.
Kevin Sussman as Stuart Bloom – Then
Kevin Sussman was introduced to the show as Stuart during the second season, as the owner of comic book store that the guys frequent in Pasadena. Though he isn’t one of the core members of the group, Stuart often pops up during their misadventures, though the character struggles even more than they do to fit in. Stuart is characterized by his often depressed demeanor that is usually the result of some mishap or another.

Kevin has been working for a long time prior to starting The Big Bang Theory.His prior roles included appearances on Ugly Betty, as well as working on the film A.I. Artificial Intelligence, which Steven Spielberg directed in 2001. Kevin’s real life isn’t exactly similar to the struggling existence he portrays at Stuart. In addition to his regular work on The Big Bang Theory, Sussman reprised his role as Steve in the Netflix series, Wet Hot American Summer: First Day of Camp in 2015.
Sara Gilbert as Leslie Winkle – Then
Sara Gilbert is another actress who got her start on Roseanne that went on to appear on The Big Bang Theory. Playing Leslie Winkle, essentially the female version of Leonard, the two got to re-live their onscreen relationship when Leonard asks Leslie out in Season 1, fearing that a girl like Penny would never go out with him. Leslie, however, often clashed with Sheldon, making the relationship difficult to maintain. Leslie would eventually go on to have a dalliance with Howard as well.

Though it has been several years since Sara has appeared on The Big Bang Theory, she is still most often recognized for her years playing Darlene Connor on Roseanne, a role she has agreed to reprise in the upcoming revival that is set to be released in 2018. Sara will also be serving as an executive producer on the new production. Sara is also the co-host of CBS’s The Talk and is married to wife Linda Perry, with whom she is raising three children.
Melissa Rauch as Bernadette Wolowitz – Then
We’re first introduced to microbiologist Bernadette in season three when Penny offers to set her up with Howard. The pair struggled to find common ground early in their relationship, until Bernadette realized that Howard’s mother was similar to her own. The two eventually married, making Howard the first of the gang to settle down and to start a family. Bernadette quickly became an integral part of the formula on The Big Bang Theory and was Penny’s first regular female companion on the show.
Melissa Rauch as Bernadette Wolowitz – Now
Melissa Rauch got her start working as a stand up comedian in New York City, while she studied acting at Marymount College. Though she had performed a successful solo show in New York City, The Big Bang Theory was her breakout role. During the course of her run on The Big Bang Theory, she has also had roles in several other TV shows and films, including True Blood and The Bronze. She also voiced Francine in 2016’s Ice Age: Collision Course.
Jim Parsons as Sheldon Cooper – Then
Sheldon has been charming audiences with his bumbling social mishaps since the very first episode of The Big Bang Theory. He works alongside Leonard at CalTech as a theoretical physicist, an occupation he often finds superior to Leonard’s experimentation. Jim Parsons perfectly captures Sheldon’s misguided sense of superiority that earned him a Ph.d at an exceptionally early age, but fails to recognize the nuance of social situations. Despite his lack of social mores, his friends continue to stick by his side.
Jim Parsons as Sheldon Cooper – Now
It can be hard to believe sometimes that Sheldon proved to be Parson’s big break, given his facile performance on the show. He has gone on to win a number of prestigious awards for playing Sheldon, including four Primetime Emmy Awards for Outstanding Lead Actor in a Comedy Series and one Golden Globe. Parsons made his Broadway debut in 2011 in A Normal Heart, and has parlayed his popularity into a salary of $900,000 per episode alongside his costars.
