It's been reported that Sheldon, the working title for The Big Bang Theory spin-off is in-development and will be about a young Sheldon Cooper. Iain Armitage will play the boy genius, and Zoe Perry will play his religious fanatic mother. Perry is the real-life daughter of Laurie Metcalf, who recurs as Sheldon's mother on The Big Bang Theory. Sheldon's father died when he was 14, long before The Big Bang Theory takes place, so there's no set template for what George Cooper, Sr. is supposed to be. All we know about George is from what other characters have said about him. We know he was kind of a redneck simpleton who liked to drink whiskey and shoot guns. We know he didn't get along with Sheldon's mother and cheated on her -- Sheldon knocks three times before entering a room because he once walked in on his father in bed with another woman. He was a jerk, but Sheldon loved him.
