Plus: Katey Sagal and Jack McBrayer join the CBS comedy — and 11 more photos!
The Big Bang Theory‘s return will be a family affair
In the season 10 premiere, Leonard (Johnny Galecki) and Penny (Kaley Cuoco) plan to renew their vows, which is made all the more difficult by the fact that Leonard’s dad (Judd Hirsch) may have slept with Sheldon’s (Jim Parsons) mom (Laurie Metcalf).
But Penny will have family drama of her own when her mother (Katey Sagal) and drug addict brother (Jack McBrayer) make their debut — and EW has the exclusive first look at the wedding family photo!
“Penny’s close with her dad [Keith Carradine],” EP Steve Molaro tells EW. “As we know, her brother Randall has been a bit of trouble over the years, selling drugs and being in and out of jail, and that’s put a lot of stress on her mom. You will pick up on the tensions between her mother and her brother very quickly, and you get a glimpse of Penny and her dad being caught in the middle of that.”
The Big Bang Theory returns Monday, Sept. 19 at 8 p.m. ET on CBS. See more photos from the season 10 premiere, which also includes the debut of Dean Norris as an Air Force representative from the Department of Materiel Command interested in the boys’ quantum gyroscope for military applications, below.
