The Big Bang Theory universe is getting even bigger! After the success of Young Sheldon, a brand-new spin-off is on the way, and this time, it’s all about everyone’s favorite underdog, Stuart Bloom. Titled Stuart Fails to Save the Universe, the upcoming sitcom will finally focus on the lovable yet perpetually unlucky comic book store owner, played by Kevin Sussman.
For years, Stuart was the go-to guy for all things nerd culture, providing the gang with comics, collectibles, and some of the most hilariously awkward moments on the show. Whether he was crashing at Howard and Bernadette’s house or struggling to keep his shop afloat, Stuart’s life was one big chaotic mess. Now, he’s getting his own series, and fans are eager to see what’s next for him.

Produced by Big Bang Theory co-creators Chuck Lorre and Bill Prady, this spin-off promises to dive deeper into Stuart’s world with plenty of geeky humor, heartwarming moments, and, of course, cameos from fan-favorite characters. Will Stuart finally catch a break? Or will his life remain one awkward disaster after another? Either way, we’re ready for the ride!
Stuart Fails to Save the Universe: Who is in the cast?
The Big Bang Theory universe is expanding; this time, it’s all about Stuart Bloom! Kevin Sussman is back as the awkward yet oddly lovable comic book store owner, finally getting the spotlight he deserves. After years of being the underdog, Stuart is ready to take center stage, hopefully with fewer life disasters (but let’s be real, probably not).
Joining him is Lauren Lapkus as Denise, the ultimate nerd-girl dream. She’s Stuart’s ride-or-die, his comic book-loving, no-nonsense girlfriend, and she’s about to bring all the sass and geek culture knowledge we need. Their chemistry? Still undefeated.
But wait, there’s more! Brian Posehn is returning as Bert Kibbler, the rock-loving (literally, he’s a geologist) awkward genius with the driest humor in Pasadena. And, of course, what’s a Big Bang Theory spin-off without John Ross Bowie as Barry Kripke? The lisping, roast-master physicist is back, and you just know he’ll be dropping savage one-liners all season long.
More cast reveals are expected soon, but with this lineup, it’s already giving geek comedy gold. Buckle up because Stuart’s chaotic journey is just getting started!
What is the spin-off about?

If you thought The Big Bang Theory had its fair share of chaos, just wait until you see Stuart Bloom navigating life on his own. The show picks up years after the original series, following Stuart as he continues running his beloved comic book store. But in true Stuart fashion, things never go quite as planned.
The show will explore Stuart’s struggles as a small business owner in an increasingly digital world, where comic book shops are fading and rent prices are rising. Between balancing his relationship with Denise, dodging financial disasters, and somehow still getting tangled up in awkward social situations, Stuart’s life is anything but smooth sailing.
Expect plenty of geek culture references, pop-culture deep dives, and hilarious guest appearances from familiar faces. Will Barry Kripke become his new landlord? Will Bert Kibbler rope him into a bizarre geology-themed side hustle? No one knows for sure, but one thing is certain—Stuart’s world is about to get a whole lot messier.
With its signature Big Bang Theory humor and underdog charm, Stuart Fails to Save the Universe might just be the spin-off we never knew we needed!
What to expect from the show?

Stuart Fails to Save the Universe is shaping up to be a must-watch for Big Bang Theory fans, offering the same brand of nerdy humor, awkward social dynamics, and heartwarming underdog moments. While the original series revolved around genius physicists navigating relationships, this spin-off flips the script. Stuart is no scientist, but his struggles with running a comic book store, maintaining a relationship, and just existing in the real world are just as entertaining.
The show is expected to feature special appearances from past Big Bang Theory cast members, though details remain under wraps. Will we see Sheldon drop in for a Fun With Flags reboot? Could Raj finally find love at Stuart’s store, of all places? Anything is possible.
As for when and where you can watch it, Stuart Fails to Save the Universe is set to premiere on CBS in mid-to-late 2025, with episodes also available for streaming on Paramount+. Given the success of Young Sheldon, CBS is betting big on this spin-off, and if it’s anything like its predecessors, we could be in for another long-running sitcom favorite.
Stuart may not save the universe, but he’ll definitely make us laugh trying!
