The official synopsis for Stuart Fails to Save the Universe proves the spinoff will bring back The Big Bang Theory's characters, but there's a catch.

Four supporting cast members from The Big Bang Theory are carrying over to Stuart Fails to Save the Universe. They are Kevin Sussman 's titular Stuart, John Ross Bowie as Barry Kripke, Brian Posehn as Bert Kibbler, and Lauren Lapkus as Stuart's girlfriend Denise.

“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.
