The favourites are finally coming back after seven years. Fans have spent years hoping for another chapter in The Big Bang Theory universe, but few expected it to arrive in the form of Stuart Fails to Save the Universe. Created by Chuck Lorre, Bill Prady and Zak Penn, the new series puts the spotlight on Stuart Bloom, the awkward comic book store owner played by Kevin Sussman. A familiar face throughout the original sitcom, Stuart often found himself caught in the middle of the gang's adventures. This time, however, he takes centre stage in a story that promises to be bigger, stranger and far more chaotic than anything seen before.Streaming details of Stuart Fails to Save the UniverseThe 10-episode series premiered on HBO Max on July 23, 2026, at 9 PM ET.
