The Big Bang Theory spin-off, Stuart Fails to Save the Universe, is taking a page out of the MCU playbook with a multiverse saga of their own.

“The Big Bang Theory,” about a group of nerdy friends ran from 2007 to May 2019. The first spinoff, “Young Sheldon,” ran for seven seasons and concluded last year. “Georgie & Mandy’s First Marriage,” will debut its second season in the fall. Warner Bros. and HBO Max are owned by CNN’s parent company.
