Stuart and his friends are hanging around for a second season. HBO Max has officially renewed Stuart Fails to Save the Universe, starring Kevin Sussman reprising his role as The Big Bang Theory‘s Stuart.
The cast also includes Lauren Lapkus as Denise, Brian Posehn as Bert, and John Ross Bowie as Barry. Season one premiered on July 23, 2026 and will finish up on September 24.
“We’re delighted with how this hilarious, genre-bending show from Chuck, Zak, and Bill has connected with the audience, both devotees of The Big Bang Theory and new fans alike,” stated Amy Gravitt, EVP, HBO Programming, Head of HBO & HBO Max Comedy Series. “Along with everyone else, we can’t wait to see the worlds they conjure for these beloved characters next season.”
Chuck Lorre, Zak Penn, and Bill Prady created the spinoff and serve as writers and executive producers.
HBO Max offers this description of the first season: “Comic book store owner Stuart Bloom is tasked with restoring reality after he breaks a device built by Sheldon and Leonard, accidentally bringing about a multiverse Armageddon. Stuart is aided in this quest by his girlfriend Denise, geologist friend Bert, and quantum physicist/all-around pain in the ass Barry Kripke. Along the way, they meet alternate-universe versions of characters we’ve come to know and love from The Big Bang Theory. As the title implies, things don’t go well.”
