The Big Bang Theory universe is officially expanding again, and this time, it’s not just Stuart Bloom stepping back into the spotlight. Warner Bros. TV has confirmed that Stuart Fails To Save The Universe will reunite fans with three major returning characters who helped make the original series so quirky and beloved.
And honestly? These returns might be the biggest reason fans are buzzing.
The Comeback of Denise, Bert & Barry — TBBT’s Most Underrated Trio
While the spinoff centers on Kevin Sussman’s eternally unlucky comic-book-store owner, the biggest surprise is that Stuart won’t be saving the universe alone.
Alongside him are three fan-favorite oddballs who carved out their own cult followings in TBBT’s later seasons:
💥 Denise (Lauren Lapkus)
Stuart’s girlfriend and resident pop-culture expert is back — a major win for fans who loved her witty one-liners, sharp comic timing, and surprisingly grounded chemistry with Stuart. Denise quickly became the best thing to happen to him in years, and her return signals that their dynamic will be a core part of the new series.
🪨 Bert Kibbler (Brian Posehn)
The lovable, soft-spoken geologist with unexpected social confidence (and unexpected prize money) is returning, too. Bert’s mix of shy charm, academic brilliance, and unintentional comedy made him one of the show’s most quietly iconic supporting characters. His presence practically guarantees meme-worthy moments.
🧠 Barry Kripke (John Ross Bowie)
No TBBT spinoff would be complete without the chaotic genius of Barry Kripke. Known for his rivalry with Sheldon, his scientific brilliance, and his unstoppable self-confidence, Kripke’s return ensures the series will bring its signature flavor of unpredictable, over-the-top fun.
These three aren’t cameos — they’re core cast members, shaping the heart and humor of the show from day one.
Will Other Original TBBT Characters Show Up?
At a recent interview with Deadline, Warner Bros. TV CEO Channing Dungey addressed the big question: could even more classic TBBT characters return?
Her answer:
“I would never say never.”
While she emphasized the studio’s focus on the new show’s regular cast (a.k.a. Stuart and his returning crew), she didn’t shut the door on future surprises.
Translation:
Cameos are definitely possible — just don’t expect them right away.
A Spinoff Built on the Franchise’s Most Overlooked Comedy Gold
Instead of revisiting the original core gang, Stuart Fails To Save The Universe is celebrating some of TBBT’s most underrated characters — the weirdos, the sidekicks, the scene-stealers who always delivered laughs.
And honestly?
That’s exactly what makes this spinoff feel fresh.
With Stuart, Denise, Bert, and Kripke leading the charge, the new series has all the ingredients for a genuinely fun, character-driven comedy that expands the TBBT world without copying the original formula.
