Katey Sagal has been tapped to play Penny’s mom Susan, while Jack McBrayer will portray her brother Randall on the new season of The Big Bang Theory, executive producer Steve Molaro revealed at the show’s Comic-Con panel on Friday.
“We are finally going to meet more of Penny’s family,” Molaro said. “We’re going to be meeting Penny’s mom and her brother in the first episode back. We’re super excited that Katey Sagal will be playing Penny’s mom.”
This isn’t the first time the Sons of Anarchy star played Kaley Cuoco’s mom on TV. The duo starred together on the ABC comedy 8 Simple Rules.
Susan is described as “stressed out and neurotic from a life with her troubled son,” which makes sense given that Randall’s character description calls him “a cheerful former drug dealer and ex-con.” At least he’s cheerful, right?
During the panel, Molaro said of 30 Rock alum McBrayer’s character, “He’s a drug dealer and he has just gotten out of prison. We needed to find the right person to get for this. I think we did a pretty good job on the casting. He’s a little scary.”

In other news, Molaro revealed that Sheldon (Jim Parsons) and Amy (Mayim Bialik) will go to a real-life flag convention in season 10. Also, as Penny ponders a job change, Molaro noted, “We believe in the world of The Big Bang Theory that that movie she did with Wil Wheaton, Serial Ape-ist, is floating around and developed a cult following. One way Penny could make money is signing autographs for fans.”
The Big Bang Theory returns Monday, Sept. 19 at 8 p.m. ET on CBS.
