Meet the New Cast: Ryan Cartwright, Josh Brener, and Tommy Walker

The latest news from Deadline reveals that Stuart Fails to Save the Universe has welcomed three recurring guest stars to the fold. If the names Ryan Cartwright, Josh Brener, and Tommy Walker ring a bell, that is because these actors already have ties to the Big Bang world — and they are ready to dive deeper into this new spinoff.

• Ryan Cartwright will play Kyle, a daily visitor of Stuart’s comic book store. Cartwright is no stranger to comedy fans, known for his work on Mom and previous guest appearances on The Big Bang Theory itself. He once guest-starred as Penny’s community college classmate, Cole, so it feels fitting that he returns to the comic book universe, albeit in a new role.

• Josh Brener is cast as Trevor. Fans might remember Brener from Silicon Valley and also from his two guest spots on The Big Bang Theory as Dale, one of the comic book store employees. His return adds an extra layer of continuity and fun for longtime viewers.

• Tommy Walker steps in as Gary, the new boyfriend of Denise, a key supporting character in the series. Walker brings his comedic chops from The Kominsky Method and is sure to add some fresh dynamics to the group.

These additions join the already confirmed main cast members: Kevin Sussman reprising his role as Stuart Bloom, Lauren Lapkus as Denise, Brian Posehn as Bert Kibbler, and John Ross Bowie as Barry Kripke.

What is Stuart Fails to Save the Universe All About?

The spinoff picks up after the events of The Big Bang Theory and focuses on Stuart Bloom, the lovable and often hapless comic book store owner who has always been a fan favorite. According to the official synopsis, Stuart accidentally breaks a device created by Sheldon and Leonard, which leads to a multiverse Armageddon. Naturally, things go sideways fast, and Stuart finds himself tasked with restoring reality itself.

Luckily, Stuart does not face this universe-saving mission alone. He is aided by Denise, Bert, and Kripke as they journey through alternate universes filled with different versions of the beloved characters fans have come to know. The promise of familiar faces with quirky twists offers endless comedic and storytelling opportunities.

As the title cheekily suggests, things do not exactly go according to plan. Expect mishaps, awkward moments, and the kind of humor that Big Bang fans crave.

How This Spinoff Fits Into the Big Bang Theory Universe

Stuart Fails to Save the Universe is the third major expansion of the Big Bang Theory franchise. It follows the massive success of the prequel Young Sheldon, which ran from 2017 to 2024, and the sequel to the prequel, Georgie & Mandy’s First Marriage, which recently started its second season.

What sets Stuart Fails to Save the Universe apart is its focus on the multiverse concept and its willingness to poke fun at the characters and situations fans already love. While Young Sheldon explored the origins of the beloved nerdy physicist, this new series is more about chaos, adventure, and the bittersweet reality of Stuart’s life.

For longtime fans, spotting Easter eggs and alternate reality versions of their favorite characters will be a major draw. For newcomers, the show offers a fresh take on classic sitcom tropes with a sci-fi twist.

Why Fans Should Be Excited About the New Cast

Adding Ryan Cartwright, Josh Brener, and Tommy Walker is a smart move for the series. Their previous ties to The Big Bang Theory give them an instant connection with the fan base while allowing them to expand on new and interesting characters. The fact that Cartwright and Brener appeared before in memorable guest roles makes their new parts feel like a natural evolution rather than a random casting choice.

Moreover, their comedic backgrounds and diverse acting experiences promise a well-rounded mix of humor styles. With this new trio, Stuart Fails to Save the Universe gains fresh faces that complement the established leads, injecting the show with energy and unpredictability.

The Big Bang Theory Universe Keeps Growing

Stuart Fails to Save the Universe is shaping up to be a must-watch for anyone who loved The Big Bang Theory or enjoys smart, quirky comedy with a sci-fi spin. The addition of Ryan Cartwright, Josh Brener, and Tommy Walker only sweetens the deal, promising plenty of laughs and unexpected moments.

If you want to stay in the loop on the latest cast updates and release info, keep an eye on HBO Max and entertainment news outlets. This spinoff is not just expanding the Big Bang Theory universe — it is giving fans a new reason to geek out all over again.

So, grab your favorite comic book, settle into your comfiest chair, and get ready for Stuart’s not-so-heroic quest to save reality. Because when Stuart tries to save the universe, failure is the only guarantee — and that is exactly what makes it so entertaining.
