Back in March, CBS officially picked up straight to series the spinoff of “The Big Bang Theory,” and Zoe Perry has a big shoe to fill in “Young Sheldon.”

The “Scandal” star will play the younger version of Sheldon Cooper’s earnestly religious mother, Mary Cooper. Laurie Metcalf played the mother in the original series, and she happens to be Perry’s mother. Metcalf was nominated for her role in the 2016 Primetime Emmy Awards for Outstanding Guest Actress in a Comedy Series.

“I went in and auditioned for the casting directors and for [executive producers] Chuck Lorre and Steve Molaro. Then, the rest is my lucky history,” Perry explained to Entertainment Weekly as she went through the typical casting process.

Iain Armitage of “Big Little Lies” will take on the titular role. The story follows the formative years of the theoretical physicist. Actor Jim Parsons, who established the character in the famous sitcom, will appear as the narrator.

Set in East Texas, nine-year-old Sheldon still lives with his parents and siblings while he attends high school.

“I did run one of the scenes with her because I was curious to hear her accent doing it,” Perry stated, describing her preparations. “Although I actually didn’t have her read the lines because then that would’ve just stuck in my head. But I made her talk a little bit and I rewatched some of her stuff,” she added.

When asked how she feels about following her mother’s footsteps, Perry said, “Daunting has always been mixed in there, but right now it’s just exciting.”

The actress is currently working alongside her father, Jeff Perry, on “Scandal.” She claimed that both her parents have inspired her.

Other cast members of the upcoming comedy show include Lance Barber, Raegan Revord, and Montana Jordan. A source informed The Hollywood Reporter that Barber will play George, Sheldon’s father. Revord will portray young Missy, Sheldon’s twin sister, while Jordan will play George Jr., the twins’ older brother.

“Young Sheldon” will premiere within the 2017–2018 CBS broadcast season.
