English actress Natalie Dormer is best known for playing beguiling femme fatales as astute as they are alluring—currently as Margaery Tyrell on “Game of Thrones,” formerly as Irene Adler on “Elementary” and Anne Boleyn on “The Tudors,” as well as “The Blonde” who seduces Brad Pitt in “The Counselor.” “I love those women that I play that have sexual power,” Dormer told The Daily Beast in an interview published today. “But I’m trying to step away from it for me, and for my artistic growth. It’s also more who I am. I’m not that woman.”
