It's not a secret that The Big Bang Theory casts family members extremely well.
So it shouldn't be a surprise that when it came time to expand Penny's world, she was given only the best.
News out of San Diego Comic Con today is that Katey Sagal will play Penny's mom and Jack McBrayer will be Penny's brother.
“We are finally going to meet more of Penny’s family,” Executive Producer Steve 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.”
He's not the only one.
This isn't the first time Cuoco and Sagal will have played mother and daughter on television.
Their first time was on the series Eight Simple Rules, which also starred John Ritter. (See photo)
Ritter died during production on that series, and Cuoco and Sagal, along with the other actors who appeared as his children, shared some of the most genuine and touching scenes as they dealt with his passing both within their TV family, and in real life.
Molaro shared a bit 30 Rock alum McBrayer's character while on stage.
“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.”
We're really looking forward to these episodes, because when family arrives on the scene on The Big Bang theory, not only is it comedic gold, but the writing and acting is so well done, it often transforms to Emmy Gold as well.
Christine Baranski and Laurie Metcalf who play Leonard's and Sheldon's moms respectively, have both been nominated for Emmys in 2016.
In other exciting news out of Comic Con, Leonard and Amy will be taking a road trip together during The Big Bang Theory Season 10.
They'll be joining the real world and getting up off the couch for trip to an actual flag convention!!
Talk about a swoon-worthy, romantic event!
