Do You Need to Watch 'The Big Bang Theory' Before 'Stuart Fails to Save the Universe'? A Complete Guide to the Spin-Off
The 10-episode HBO Max series shifts into science fiction and fantasy, with a familiar face turned into a 60-foot witch.
- On Thursday, July 23, 2026, the Big Bang Theory spinoff Stuart Fails to Save the Universe debuts on HBO Max, with co-creator Chuck Lorre selecting Kevin Sussman to lead the series as the reluctant hero Stuart Bloom.
- Lorre explained that the minor character was "the absolute worst choice" to lead an action-adventure series, which ultimately made him the "perfect choice" after Stuart accidentally triggers a "multiverse armageddon."
- Stuart reunites with Denise , Bert , and Kripke to navigate alternate dimensions after damaging a device built by Sheldon Cooper and Leonard Hofstadter.
- Co-Creators Zak Penn and Bill Prady designed the 10-episode series to intentionally defy franchise lore, with Prady noting, "One of the wonderful things about moving from universe to universe is you're not obligated to be consistent."
- Critic Tom Chang awarded the series 8/10, noting its fun multiverse travel, though the show's future success depends on potential renewal by HBO Max.
