HBO Max announced today that Stuart Fails to Save the Universe has been renewed for a second season. The early pickup comes four episodes into the comedy's 10-episode freshman run.

"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," said 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, Zak, and Bill delivered something truly special with STUART FAILS TO SAVE THE UNIVERSE - a completely original take on one of the most beloved franchises of all time that captures the unique essence that made 'The Big Bang Theory' so special," said Channing Dungey, Chairman and CEO, Warner Bros. Television Group and WBD US Networks. "It's been an absolute joy to see audiences embrace this next iteration so passionately, and we can't wait to continue exploring the multiverse in season two."

The series follows comic book store owner Stuart Bloom, who 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.
