With the news of a Big Bang Theory spin-off having just been confirmed the other month, there's more exciting news on the horizon for Stuart Fails to Save the Universe.

It's been announced (via Deadline) that Ryan Cartwright (Kevin Can Wait), Josh Brener (Silicon Valley), and Tommy Walker (Danger Force) are set for major recurring roles in the series. If you feel as though a couple of those names seem familiar to the world of Big Bang, that's because they are—both Cartwright and Brener have had minor roles in the comedy.

Unlike previously announced cast members Kevin Sussman, Lauren Lapkus, Brian Posehn, and John Ross Bowie, Brener and Cartwright will not be reprising their former Big Bang roles. It would certainly be quite a deep-cut move for the series if they were going to, especially seeing as Cartwright only appeared in a guest star spot in season 6 and Brener similarly just appeared in two episodes (in seasons 5 and 6).

According to Deadline, Cartwright will be playing Kyle in the new series, who is "believed to be a comic book nerd and a daily patron of Stuart’s bookstore." Walker will play Gary, who is said to be "Denise’s handsome new boyfriend," and Brener will play Trevor.

Set in the future, Stuart Fails to Save the Universe will center on comic book shop owner Stuart Bloom (played by Kevin Sussman), who is "tasked with restoring reality after he breaks a device built by Sheldon and Leonard, accidentally bringing about a multiverse Armageddon," according to the official synopsis.

It continues: "Stuart is aided in this quest by his girlfriend Denise [Lauren Lapkus], geologist friend Bert [Brian Posehn], and quantum physicist/all-around pain in the ass Barry Kripke [John Ross Bowie]. "Along the way, they meet alternate-universe versions of characters we've come to know and love from The Big Bang Theory. As the title implies, things don't go well."
