Ryan Cartwright (Kevin Can Wait), Josh Brener (Silicon Valley) and Tommy Walker (Danger Force) are set for major recurring roles on HBO Max’s upcoming "The Big Bang Theory" spinoff series "Stuart Fails to Save the Universe", which stars the mothership series’ Kevin Sussman, Lauren Lapkus, Brian Posehn and John Ross Bowie.

Like Sussman, Lapkus, Posehn and Bowie, Cartwright and Brener also are "Big Bang" alums. Unlike the trio, they will not be reprising their roles.



Cartwright will be playing Kyle, believed to be a comic book nerd and a daily patron of Stuart’s book store.

Cartwright did a one-off guest spot in a Season 6 episode as a British student in Penny’s (Kaley Cuoco) history class at Pasadena Community College, who makes Leonard (Johnny Galecki) jealous.



Brener plays Trevor.

Brener appeared in two episodes — one in Season 5 and one in Season 6 — as Stuart’s (Sussman) friend and co-worker Dale.



Tommy Walker will play Gary, said to be Denise’s handsome new boyfriend.
