When The Big Bang Theory first hit the screen in 2007, it didn’t take long for it to become one of the most loved sitcoms out there. With its quirky characters, catchy theme song, and funny yet heartwarming stories, the show quickly won over tons of fans and went on for 12 awesome seasons.
Even though the popular prequel Young Sheldon is still going strong and there are rumors about a new spinoff, fans were still pretty bummed when the original show wrapped up in 2019.
So, what have the cast been up to since then? From welcoming babies to appearing on Jeopardy! and taking some much-needed time off — here’s a look at what the Big Bang Theory stars have been doing in the years after the show ended.
Jim Parsons
Since saying goodbye to his legendary role as Sheldon Cooper on The Big Bang Theory, Jim Parsons has been anything but quiet. He quickly proved he’s more than just a quirky genius by starring in the touching romantic drama Spoiler Alert (2022), a film that showed off his emotional depth and won him a lot of new fans. But Jim didn’t stop there — he stepped behind the camera as a producer, teaming up once again with his Big Bang Theory co-star Mayim Bialik on the popular comedy series Call Me Kat. Their reunion gave fans all the nostalgia vibes while showing off their great chemistry off-screen too.
What’s more, Jim has stayed connected to the Big Bang family by continuing his role as the narrator on the spinoff Young Sheldon, keeping that familiar voice alive for longtime fans. Beyond acting and producing, Jim has been exploring a variety of new projects in both film and television, challenging himself with roles that go far beyond what made him famous.
By 2025, Jim Parsons has really proven he’s not just a one-hit wonder but a versatile actor and creative force in Hollywood. Whether he’s delivering sharp performances, producing fresh shows, or lending his voice to beloved characters, he’s kept his star power shining strong and continues to surprise and impress audiences everywhere.
Kaley Cuoco
Kaley Cuoco has come a long way since her days as the girl next door on The Big Bang Theory. After the show ended in 2019, she didn’t miss a beat — jumping straight into bigger, bolder roles that showed just how much range she really has. Her breakout moment post-Big Bang came with The Flight Attendant, a dark comedy-thriller where she not only starred but also produced. The show was a huge hit and even earned her Emmy and Golden Globe nominations, officially putting her on the map as a serious actress and creative force.
Kaley didn’t stop there. She continued to build her production company and took on voice acting too, most notably as the chaotic and hilarious Harley Quinn in the animated series — a fan-favorite that’s still going strong. On top of that, she’s starred in several film projects, including the romantic comedy Meet Cute (2022), and kept fans excited with her upcoming roles in both drama and comedy.
By 2025, Kaley has fully stepped out of Penny’s shadow and built a name for herself as one of the most versatile and driven women in Hollywood — and it’s clear she’s just getting started
Johnny Galecki
Johnny Galecki, best known as the lovable and slightly awkward Leonard Hofstadter on The Big Bang Theory, has kept things a bit more low-key since the show wrapped in 2019 — but that doesn’t mean he disappeared. After over a decade of playing one of TV’s most iconic nerds, Johnny shifted gears to focus more on his personal life, welcoming his first child in 2019 and stepping back a bit from the Hollywood spotlight to enjoy fatherhood. Still, he’s popped up in a few exciting ways. In 2023, he returned to the producer’s chair, working behind the scenes on some indie projects, and has been developing new content through his own production company. Fans were also thrilled when he made a surprise guest appearance in a Young Sheldon flash-forward moment — a nostalgic nod that had longtime viewers buzzing.
By 2025, while Johnny may not be chasing constant headlines, he’s clearly choosing projects that matter to him and continuing to leave his mark on the industry — just in a quieter, more intentional way. And for fans who grew up watching Leonard fumble through love and science, there’s something kind of cool about seeing Johnny enjoy life at his own pace, while still keeping the door open for the occasional comeback.
Simon Helberg
Simon Helberg, who brought the eccentric and hilariously overdressed Howard Wolowitz to life on The Big Bang Theory, has quietly built a solid post-sitcom career that’s all about range and depth. After the show ended, Simon pivoted into more dramatic and indie roles, reminding everyone that he’s not just a sitcom star — he’s a seriously talented actor. One of his biggest post-Big Bang moments came with his role in Annette (2021), where he starred alongside Adam Driver and Marion Cotillard. The film premiered at Cannes, and Simon’s performance as a quirky, emotionally complex conductor earned major critical praise.
Since then, he’s taken on a mix of unique film projects, voice acting roles, and even a return to the stage — something he’s always loved. By 2025, Simon has become known as a bit of a chameleon in the industry: low-key, incredibly talented, and always popping up in unexpected, artsy roles that challenge the typical “sitcom alum” path. While he may have traded Howard’s turtlenecks and belt buckles for more grounded characters, fans still light up whenever he makes an appearance — proving that Simon’s blend of charm, wit, and emotional depth never goes out of style.
Mayim Bialik
Mayim Bialik, who played the brilliantly awkward Amy Farrah Fowler on The Big Bang Theory, has had one of the most interesting and multi-layered careers post-show — both on and off screen. After Big Bang wrapped, Mayim kept the momentum going with a mix of acting, producing, writing, and even hosting. She reunited with co-star Jim Parsons in Call Me Kat, a quirky comedy where she not only starred but also served as executive producer. The show ran for three seasons and showed off her charm in a whole new light.
But that’s just the start. In 2021, Mayim made headlines as one of the guest hosts — and later co-hosts — of Jeopardy!, stepping into some very big shoes and impressing fans with her brainy energy and natural stage presence. Although her hosting run ended in 2023, it reminded everyone of her real-life PhD in neuroscience — and made her one of the few stars who could literally host Jeopardy! and star in a sitcom at the same time.
By 2025, Mayim continues to be a powerful voice in entertainment and beyond. She’s hosted a popular podcast (Mayim Bialik’s Breakdown), spoken openly about mental health, and used her platform to advocate for science, women in STEM, and Jewish identity. Whether she’s acting, writing, or breaking down the human brain one episode at a time, Mayim Bialik is proof that being smart is seriously cool — and she’s not slowing down anytime soon.
Kunal Nayyar
Kunal Nayyar, forever remembered as the shy-yet-lovable Raj Koothrappali from The Big Bang Theory, has completely flipped the script on his career since the show ended. While fans knew him for his comedic charm, Kunal’s post-Big Bang choices have been all about showing off his dramatic range — and it’s paid off big time. One of his standout performances came in Netflix’s dark crime series Criminal: UK (2019), where he shocked viewers with a chilling, serious role that was miles away from the sweet, awkward Raj we all knew. That moment proved he wasn’t afraid to take risks, and audiences were here for it.
Since then, Kunal has taken on a mix of film and TV projects, including roles in Suspicion (2022), alongside Uma Thurman, and several international productions that highlight his versatility. He’s also lent his voice to animated films and continued to be a presence in both Hollywood and the UK entertainment scene. By 2025, Kunal is seen as a dynamic, international actor — balancing drama, thrillers, and the occasional return to comedy — all while staying connected to his roots and fans around the globe.
While he might not be navigating awkward conversations with women on-screen anymore, Kunal Nayyar’s real-life career glow-up is something very worth talking about.
Melissa Rauch
Melissa Rauch, who stole the show as the tiny-but-fierce Bernadette Rostenkowski-Wolowitz on The Big Bang Theory, has been making some seriously impressive moves since the series wrapped. While many fans knew her for her sharp comedic timing and powerhouse voice, Melissa has taken her talents to a whole new level — both in front of and behind the camera. One of her biggest post-Big Bang wins came in 2023 when she took the lead role — and executive producer credit — on NBC’s reboot of the classic courtroom comedy Night Court. Not only did she step into the shoes of Judge Abby Stone (daughter of the original show’s lead), but she also helped revive the series with a fresh twist that really landed with both longtime fans and new viewers.
Beyond that, Melissa has continued doing voice work, lending her talents to animated shows and films, and remains a creative force in comedy. She’s also been building her reputation as a producer, working on projects through her production company alongside her husband, Winston Rauch. By 2025, Melissa has clearly cemented herself as more than just a sitcom star — she’s now seen as a multifaceted talent who’s calling the shots, creating stories, and still making people laugh in the process.
Whether she’s rocking a gavel or a voice role, Melissa Rauch continues to prove that big things come in small, very funny packages.
