Stuart Fails to Save the Universe, the upcoming The Big Bang Theory spin-off, will debut this July on HBO Max, it was revealed yesterday.

The announcement came during a panel at CCXP Mexico City, where stars Kevin Sussman, Lauren Lapkus, Brian Posehn and John Ross Bowie shared new concept art and first-look stills from the show. An official Instagram account, @stuartfails, was also launched alongside the reveal.

The hour-long comedy follows hapless comic book store owner Stuart Bloom as he attempts to restore reality after accidentally breaking a device built by Sheldon and Leonard, triggering a multiverse catastrophe. Joining him on his quest are his girlfriend Denise (Lapkus), geologist Bert (Posehn), and ever-irritating quantum physicist Barry Kripke (Bowie). Along the way, the group encounters alternate-universe versions of familiar characters from The Big Bang Theory. As the title suggests, things don’t always go to plan.

Blending comedy with science fiction and fantasy, the series marks a notable shift from the traditional multi-camera format of The Big Bang Theory, adopting a more cinematic style with larger-scale settings and extensive visual effects.

The newly released teaser images show the group navigating increasingly chaotic situations, from the familiar confines of Stuart’s comic book store to a Caltech lab, where he is seen holding the device, and later a war-torn environment patrolled by armed soldiers, still carrying it. Another image shows Stuart and Denise in a tranquil lakeside setting, offering a brief contrast to the surrounding chaos, while the final shot depicts the group looking battle-worn and on edge.

It was also announced that Emmy and Grammy Award winner Danny Elfman will compose the show’s original theme music. Elfman is known for his work on films such as Beetlejuice, Edward Scissorhands, and Batman Returns, as well as television themes including The Simpsons and Desperate Housewives.

Stuart Fails to Save the Universe comes from executive producers Chuck Lorre and Bill Prady, co-creators of The Big Bang Theory, alongside Ready Player One screenwriter Zak Penn. The first season will consist of 10 episodes, with a specific July premiere date yet to be announced.
