Josh O'Connor's been on our radar for a while, not least because of his role in ITV's The Durrels and a career-making performance in 2017's God's Own Country. But 2019 is the year he'll become a household name, thanks to the fact he's taking on the role of Prince Charles in Netflix's big budget drama The Crown. He'll also tackle one of Jane Austen's more divisive creations when he plays Mr. Elton in a new adaptation of Emma.
