After initial stars were announced for the project, the next “The Big Bang Theory” spinoff has received the green light. A title has already been decided.
Twelve seasons, 279 episodes, numerous awards, and even more fans worldwide–that’s the impressive record of “The Big Bang Theory.” The sitcom about nerdy scientists ended in 2019 after twelve years but remains popular today. Established and upcoming spin-offs ensure the characters are not forgotten. A new “The Big Bang Theory” spin-off has now been officially confirmed and can go into production.
New “The Big Bang Theory” Spin-off Focuses on Stuart
The project has been planned since 2023, and until recently, it was unclear if it would even reach the production phase. Previously, Kevin Sussman, Brian Posehn, and Lauren Lapkus were announced as returning stars from the main series. However, an official confirmation for the new “The Big Bang Theory” spin-off was missing–until now. As reported by the U.S. industry magazine “Variety,” there’s now a green light for Warner’s streaming service HBO Max.
The official title is “Stuart Fails to Save the Universe,” suggesting that the comic book seller Stuart (Sussman) from “Big Bang” will be the focus this time. Lapkus will reprise her role as his girlfriend Denise, while Posehn will return as geologist Bert. Also joining is John Ross Bowie as the annoying physicist and Sheldon Cooper’s nemesis, Barry Kripke.
What “Stuart Fails to Save the Universe” Will Be About
For the first time, there are official details about the content of the upcoming “The Big Bang Theory” spin-off: Stuart accidentally breaks a device invented by Leonard and Sheldon. This mishap leads to multidimensional chaos that Stuart must resolve with the help of Denise, Barry, and Bert. During their adventures, they encounter alternative versions of characters already known from the main series.
Chuck Lorre and Bill Prady, creators of “The Big Bang Theory,” will return as producers. They will be joined by screenwriter Zak Penn, who has previously worked on “The Avengers” and Spielberg’s “Ready Player One.”

Which Guest Stars Will Appear?
It is currently unknown which familiar faces from “Big Bang” will also make a return. The official synopsis suggests at least a guest appearance by Johnny Galecki (Leonard) and Jim Parsons (Sheldon), as their invention lays the foundation for the plot. Given the premise, it’s quite likely that fans can look forward to a reunion with hopefully all the stars from back then–including Kaley Cuoco as Penny, Melissa Rauch (Bernadette), or Mayim Bialik (Amy).
Meanwhile, Lorre promises a completely different aesthetic compared to the original series: “There are a lot of computer effects,” the series creator revealed. There’s a lot of “special technical stuff” because elements of science and fantasy are incorporated. “Stuart Fails to Save the Universe” is intended to be a series that the nerds from “The Big Bang Theory” would have loved, hated, and debated.
When the new spin-off will be released is not yet foreseeable. However, it is clear that it will initially launch exclusively on HBO Max. Warner’s streaming service is set to finally start in Germany in 2026–six years after its introduction in the U.S.
