Williams earned an Oscar nod for her performance in My Week with Marilyn, a role that required the biggest physical transformation of her career.

"The expectation to be beautiful always makes me feel ugly because I feel like I can’t live up to it," Williams told Vogue of playing the iconic film star.



Already celebrated for her gamine good looks, Williams's metamorphosis into a sex symbol awed her costars, among them Kenneth Branagh, who said, "I’d look over and there is Michelle. Half an hour later, Marilyn has arrived."
