You may have hated Iain Armitage when he played the evil kid in Big Little Lies but you can’t help loving him as Sheldon Cooper in the hit comedy series Young Sheldon. And in person he’s twice as lovable.

He’s slightly older than the character he plays on TV but that works to his advantage. He’s likely to be playing his pre-adolescence for the next few years.
