Asa Butterfield graduated from child (super)star to bright young thing thanks to his starring role in Netflix's Sex Education. We don't blame you if you didn't realise that Otis is actually that cute kid from The Boy in the Striped Pajamas and Hugo. Sex Education returns for a second series this year, but Asa will also be hitting the big screen. He's set to star in The Liar, based on Stephen Fry's novel of the same name.
