Jim Parsons Reveals How He Picked Mini-Him Iain Ermitage for 'Young Sheldon'!

Jim Parsons made an appearance on Jimmy Kimmel Live! on Wednesday (August 9), and revealed what made him choose Iain Ermitage as the actor who will play young Sheldon Cooper in The Big Bang Theory‘s spin-off series Young Sheldon.

“They wrote the most trial-by-fire, two-page monologue and all these kids were coming in with it and they were all really good,” the 44-year-old actor told Jimmy. “But Iain, when his tape came in, it was mind-blowing and I thought, ‘he looks really young but he must be 13 to be able to do this’ – but he was 8.”

“He is such a man-child. He thinks like a man,” Jim added. “He’s fantastic. I didn’t think I was very good with kids but I’m fine with him. He’s such a sweet kid, too.”
