HBO Max launches 'Stuart Can't Save the Universe' spin‑off of The Big Bang Theory

HBO Max will premiere a new original comedy series, Stuart Can't Save the Universe, on July 23. The show is a spin‑off of The Big Bang Theory featuring Kevin Sussman reprising his role as comic‑shop owner Stuart Bloom. After accidentally breaking a device built by Sheldon and Leonard, Stuart is tasked with repairing a multiversal apocalypse.

The series adds a supporting cast that includes Lauren Lapkus as Denise, Brian Posehn as geologist Bert, and John Ross Bowie as the irksome quantum physicist Barry Kripke. It promises alternate‑universe versions of familiar characters, cameo opportunities and a blend of sitcom humor with sci‑fi chaos, aiming to recapture the spirit of the original sitcom on a larger, fantastical scale.
