What Is Stuart Fails to Save the Universe?
The new comedy series is the third spinoff in the Big Bang Theory universe, following Young Sheldon and Georgie & Mandy’s First Marriage. Created by Chuck Lorre, Zak Penn, and Bill Prady, the show takes the franchise into brand-new territory, as comic book store owner Stuart Bloom, played by Kevin Sussman, travels across the multiverse to prevent an Armageddon-like disaster.
Stuart is tapped to help repair a device built by Howard Wolowitz (Simon Helberg), Sheldon Cooper (Jim Parsons), and Leonard Hofstadter (Johnny Galecki) that accidentally triggers a multiverse catastrophe.
Joined by his girlfriend Denise (Lauren Lapkus), geologist friend Bert (Brian Posehn), and quantum physicist/all-around pain-in-the-ass Barry Kripke (John Ross Bowie), Stuart travels to a new alternate reality in each episode.

A Speedy, Early Renewal
The pickup for the Big Bang Theory spinoff comes four weeks into its 10-episode first season, which HBO Max says is among its biggest comedy debuts worldwide.
From creators Chuck Lorre, Zak Penn, and Bill Prady and Warner Bros. TV, the first season of Stuart Fails to Save the Universe is HBO Max’s second-biggest comedy launch ever globally, per the streamer. Not surprisingly, HBO Max’s biggest comedy launch was also a followup to a hugely popular series — Sex and the City sequel And Just Like That…
The renewal comes four episodes into Season 1’s run; episodes drop weekly every Thursday. Season 1 of Stuart Fails to Save the Universe premiered on July 23 and will have its finale on September 24.
Season 1 Cast: Returning Big Bang Faces
One of the biggest draws of the show has been its parade of returning Big Bang Theory favourites appearing in alternate-universe versions of themselves.
Over the course of its first four episodes, the HBO Max comedy has already welcomed back legacy cast members Kunal Nayyar as Rajesh “Raj” Koothrappali (in Episode 1), Kaley Cuoco as Penny (in Episode 2), Melissa Rauch as Bernadette Rostenkowski (in Episode 3), and Mayim Bialik as Amy Farrah Fowler (in Episode 4) — and that’s just a few of the familiar faces who have resurfaced across multiple universes.
