From an article on Deadline. Stuart Fails to Save the Universe, from Chuck Lorre Productions in association with Warner Bros. Television, extends the trend of every Big Bang Theory spinoff being named after its main character(s), following in the footsteps of Young Sheldon and its offshoot Georgie & Mandy’s First Marriage.
On Stuart Fails to Save the Universe, Sussman is joined by fellow Big Bang alums Lauren Lapkus, who plays Stuart’s girlfriend Denise, Brian Posehn (Bert Kibbler) and John Ross Bowie (Barry Kripke). Because the series is still awaiting a green light, the quartet are not formally cast in it but have talent holding deals with WBTV with the purpose of starring in the spinoff once it’s picked up.
The new series is written and executive produced by Chuck Lorre, co-creator and executive producer of Big Bang and all of its spinoffs to date, Zak Penn and Big Bang co-creator Bill Prady.
From the moment the Big Bang spinoff was unveiled in April 2023, there has been speculation that it may revolve around Stuart Bloom (Sussman) and his comic book store. While a reliable source of comic relief, the kind-hearted Stuart often was lonely and depressed as he strived to belong and be part of the Big Bang gang. Things started looking up for him when he met Denise. He also became close friends with Raj in Season 6 of the blockbuster mothership series.
