Comic-Con: 'Big Bang Theory' Casts Katey Sagal, Jack McBrayer
Prepare to meet some additional family members on CBS' The Big Bang Theory.
Producers behind the nerdy comedy announced Friday at Comic-Con that Sons of Anarchy's Katey Sagal will play Penny's (Kaley Cuoco) mother, Susan, and the series will also be introducing Penny's brother, Randall. Penny's brother will be played by 30 Rock grad Jack McBrayer, who made a surprise appearance to wrap Friday's panel. Both will appear in the season 10 premiere.
Penny's brother has been referenced multiple times. He's said to have worked in a meth lab and been in prison. During the panel, moderator Melissa Rauch (Bernadette) asked him if he'd ever been to jail, with McBrayer joking, "Recreationally ... I look good in orange. I'm good at making new friends!" Randall is described as a cheerful former drug dealer and ex-con.
Howard's mother, meanwhile, was a staple on the series, though she never appeared on-screen. She was voiced by the late and great Carol Ann Susi.
Sagal's credits include ABC's upcoming Dirty Dancing, Pitch Perfect 2, Futurama and The Bastard Executioner. She's repped by WME. McBrayer, a five-time Emmy nominee, is repped by UTA.
Big Bang Theory returns Sept. 19 on CBS.
