The story follows Stuart Bloom after an accident that throws reality into disarray. By breaking a device designed by Sheldon and Leonard, he triggers a multiverse-wide catastrophe and must try to repair the fallout. To do so, he’s joined by Denise, his girlfriend, Bert, his geologist friend, and Barry Kripke, a quantum physicist as brilliant as he is hard to bear.
This spin-off reintroduces several supporting characters from The Big Bang Theory while shifting the show's universe into a science-fiction comedy. The multiverse premise lets the series explore alternate realities and bring back the geeky imagination that was already part of the original.
Kevin Sussman returns to the role of Stuart, alongside Laur en Lapkus as Denise, Brian Posehn as Bert, and John Ross Bowie as Barry Kripke. The series is created, written and produced by Chuck Lorre, Zak Penn and Bill Prady, with production handled by Chuck Lorre Productions in association with Warner Bros. Television.
Another detail confirmed: the original score is by Danny Elfman. The composer, an Emmy and Grammy winner, is particularly associated with a variety of fantastical and superhero worlds in film and television.
With a multiverse-tinged premise and a lead character drawn from the fringes of the original series, Stuart Fails to Save the Universe is aimed first and foremost at fans of The Big Bang Theory. The show could also appeal to viewers who enjoy sci‑fi comedies built around paradoxes, alternate realities, and science catastrophes that go off the rails.
The official trailer for Stuart Fails to Save the Universe gives us the first glimpse of this new expansion to the The Big Bang Theory universe.
