The Big Bang Theory spinoff Stuart Fails to Save the Universe showed its first look at CCXP Mexico City, with Kevin Sussman, Lauren Lapkus, Brian Posehn and John Ross Bowie on hand to unveil the HBO Max series. The show is set to begin streaming in July.
The new chapter follows Stuart Bloom, the comic book store owner Sussman played on The Big Bang Theory, after he breaks a device Sheldon and Leonard built and sparks a multiverse armageddon. Danny Elfman will create the original theme song.
At CCXP Mexico City, the cast teased how far the series pushes Stuart from the sidelines of the original show into the center of the action. Sussman said Stuart takes on a leadership role, while adding that he is not very good at it and is far outside his comfort zone.
Posehn, who plays Stuart’s geologist buddy Bert, summed up the appeal more bluntly: the fun is watching him fail every week. Lapkus returns as Denise, Stuart’s girlfriend, and Bowie is back as the irritating quantum physicist Barry Kripke, with all three joining Stuart as the story sends them into alternate-universe versions of familiar Big Bang Theory characters.
That multiverse setup gives the series a built-in reason to revisit a world that ended on CBS in 2019 after 12 seasons, and it also extends a franchise that already produced Young Sheldon, which ended in 2024 after seven seasons. Georgie & Mandy’s First Marriage is now in its second season on CBS, keeping the wider universe active even as this new spinoff prepares to take over HBO Max in July.
The question is no longer whether The Big Bang Theory can generate another offshoot. With Stuart Fails to Save the Universe, the franchise is betting that a character once used for a comic-book-shop scene can carry the story into a full-blown catastrophe, and the first look suggests it is ready to try.
