A new spinoff for The Big Bang Theory is currently in the works at Warner Bros, and while much remains a mystery, there are still several important details already revealed. As Young Sheldon proved, shows like The Big Bang Theory are essentially the perfect formula for spinoff projects, with their wide cast of characters that audiences will always want to know more about, whether that’s in the future or the past. Although it’s unclear who the protagonist of this new spinoff is going to be, there are countless options from the original show that could be worthy candidates.
Young Sheldon was the first spinoff in the Big Bang Theory universe, and was a huge success both critically and commercially. The show follows a younger version of The Big Bang Theory’s Sheldon Cooper as he navigates teenage life and learns to find his place in a world that’s often unwilling to accept him. Despite displaying a different tone from the original sitcom, the show was a ratings juggernaut and added something new by enriching the history of the title character. While details are slim, it’s likely that The Big Bang Theory spinoff will aim to repeat that formula.

An Original TBBT Star Joins The Spinoff
the spinoff is assembling an ensemble of supporting characters who are only peripherally connected to the TBBT mainstays.
As development plugs away behind-the-scenes, the latest news finds an original series actor joining The Big Bang Theory spinoffs. Alongside previously announced stars like Kevin Sussman, Brian Posehn, and Lauren Lapkus, John Ross Bowie is now set to reprise his role as Barry Kripke. Bowie’s Kripke character first appeared in season 2, and was a colleague of Sheldon and Leonard at Caltech. Though the show’s plot is still unknown, it seems as if the spinoff is assembling an ensemble of supporting characters who are only peripherally connected to the TBBT mainstays.
The Big Bang Theory Spinoff Is In Development
The Spinoff Still Hasn’t Secured A Green Light
with TBBT co-creator Bill Prady and writer Zak Penn onboard, the development has taken another big step toward becoming reality.
The existence of another Big Bang Theory spinoff was officially announced on April 12, 2023, just as Young Sheldon was approaching the end of its sixth season (via Screen Rant). Almost nothing was given away regarding the show’s story or cast, but the most important information was that Chuck Lorre would be returning to oversee the project. However, Lorre walked back the previous announcement in November 2023, when he made it clear that no plan was in the works. How the misinformation was spread is unclear, but the fate of the Big Bang Theory spinoff is unclear at this point.
Lorre would again contradict himself when, in July 2024, he mentioned that the spinoff of The Big Bang Theory was still in the earliest stages of development. Eventually, cast members began signing on for the spinoff in October 2024, but details still remain scant. Even with the project being slowly developed, there’s no guarantee that it will ever actually get green-lit. However, with TBBT co-creator Bill Prady and writer Zak Penn onboard, the development has taken another big step toward becoming reality.
The Big Bang Theory TV Spinoff Cast
Several Original Stars Are Already Signed On
The cast of The Big Bang Theory’s upcoming spinoff remains largely unknown, but it’s likely that some of the original main cast members will be reprising their roles. Supporting actor Kevin Sussman has signed on to reprise his role as comic book shop owner Stuart Bloom, and he’s joined by Lauren Lapkus as the store’s assistant manager and Stuart’s girlfriend, Denise. Furthermore, Brian Posehn will be back as CalTech professor Bert Kibbler. In February 2025, John Ross Bowie signed on to reprise his role as Barry Kripke, Sheldon and Leonard’s colleague from CalTech.
Kevin Sussman appeared in over 80 episodes of The Big Bang Theory.
The cast list suggests the spinoff will take place after the events of the original series, and characters such as Stuart, Howard, and Raj make the most obvious candidates to return. Their humor could easily lead the series forward, and it would give viewers a chance to learn more about the main cast without tampering with the original series’ continuity. On the other hand, by focusing on another band of outsiders, the spinoff could continue the themes of TBBT with a new main ensemble.

Using the conclusion of the original sitcom as a frame of reference, there are certain characters and storylines that seem more likely to make an appearance than others. The show’s main characters, such as Sheldon, Amy, and Leonard, had their arcs concisely wrapped up in the final episode, so it’s unlikely that there’s enough material there to lead an entire TV show (particularly if Lorre wants his project to run for several seasons as Young Sheldon did). Therefore, it would have to focus on an area of the show that was left somewhat open-ended.
One option could be a project focused on Howard and Raj, as they’ve often been the comedic duo at the center of the show. Many fans were also dissatisfied with the way Raj’s story concluded in the show’s finale, as he was robbed of the happy ending that he’d always been searching for. Making him the protagonist of the spinoff could offer him an opportunity to find his person, doing justice to his character, and providing plenty of laughs along the way. This would also open the door for several other The Big Bang Theory cast members to appear.
