“The Big Bang Theory” may have ended, but it lives on in the form of several spinoffs. Given the success of prequels “Young Sheldon” (2017-2024) and “Georgie & Mandie’s First Marriage” (2024-present), perhaps it’s no surprise that a third “Big Bang Theory” spinoff is coming.

So far, the casting of only four actors is known in Stuart Fails to Save the Universe. Kevin Sussman is reprising his role as Stuart Bloom. Sussman was a series regular in The Big Bang Theory from season 6, and most recently appeared in Brie Larson's hit Apple TV+ series, Lessons in Chemistry.
