HBO Max premiered "Stuart Fails to Save the Universe" on July 23, 2026, marking the streaming launch of a 10-episode spinoff of CBS's long-running sitcom "The Big Bang Theory." New episodes will be released weekly, with the premiere slot at 9 p.m. on Thursdays for the next 10 weeks.

Premise and production approach

The series follows comic-book shop owner Stuart Bloom, played by Kevin Sussman, who is tasked with restoring reality after breaking a quantum-interference device built by Sheldon and Leonard, an act that unleashes a multiverse crisis. Creators Chuck Lorre, Bill Prady, and Zak Penn moved the franchise from a traditional multi-camera sitcom format to single-camera production to enable heavier visual effects, variable episode runtimes between 15 and 25 minutes, and stronger language and gore. Danny Elfman composed the theme song, and the opening credits change with each episode.

Cast and tone

Stuart is joined by girlfriend Denise (Lauren Lapkus), geologist Bert Kibbler (Brian Posehn), and physicist frenemy Barry Kripke (John Ross Bowie). The premise sends the quartet through a different alternate reality each episode, ranging from a Kripke-led fascist regime to a Matrix-like world. Early reviews highlighted the show's inventiveness and visual ambition while noting uneven tone and episodic inconsistency, and described the result as a multiverse satire that is also a self-aware critique of the multiverse genre.
