The Next Big Bang Theory Sequel Just Revealed the Weirdest Character Upgrade of All Time

by

A surprising new show is expanding the world of The Big Bang Theory. Creators Chuck Lorre and Bill Prady are reuniting to continue the comedy they began in 2007. While Young Sheldon and Georgie & Mandy’s First Marriage focus on the past and the Cooper family, this new series will move the story forward with some returning characters from The Big Bang Theory embarking on a fresh, unique journey.

Kevin Sussman will reprise his role as Stuart Bloom in Stuart Fails to Save the Universe, which is bringing back Lauren Lapkus as Denise, Brian Posehn as Bert Kibbler, and John Ross Bowie as Barry Kripke. This new series will be a sci-fi adventure – a departure from The Big Bang Theory and its previous spin-offs – following the group as they travel through the multiverse to protect reality. With the show’s HBO Max release date approaching, promotion is increasing, and a new promo reveals another returning face: Wil Wheaton.

Keep an eye out around the 30-second mark of the video for Wheaton’s quick appearance! However, it’s not the usual version of him – this time, he’s a superpowered character from Stuart Fails to Save the Universe, actively causing trouble for Stuart and the team. You can spot him wreaking havoc within a copy of the iconic The Big Bang Theory comic book.

What Wil Wheaton’s Stuart Fails To Save The Universe Means For TBBT

Wil Wheaton appeared on The Big Bang Theory playing a heightened version of himself, capitalizing on his existing popularity within the science fiction and comic book fan community. His dynamic with Sheldon Cooper was especially interesting, shifting from competition to friendship and back to playful rivalry over time. Ultimately, he landed the highly sought-after role of the new Professor Proton at the show’s conclusion.

Before it was officially announced, we predicted Will Wheaton would return in the new series, Stuart Fails to Save the Universe. His appearance opens the door for other guest stars, though it’s still uncertain if any of the original main cast will make even a brief appearance. Bringing back familiar supporting characters and giving them updated storylines is a smart way to grow the Big Bang Theory universe. It could also attract new viewers who weren’t fans of the original show.

Stuart Fails to Save the Universe drops all 10 episodes on July 23, 2026, on HBO Max.
