Keira Knightley Happy to Go Nude on Film. Audiences Not So Happy.

Keira Knightley has no problem appearing in the buff for her latest film. In fact, she says it’s becoming a habit.

“I always bare my breasts,” she said at the press conference to promote The Edge of Love Wednesday at the Edinburgh International Film Festival. “It’s not like it’s only in this film!”

The British actress, 23, is best known for the Pirates of the Caribbean films; last year she went au naturale in the period drama Atonement.

Referring to a scene in the wartime romance The Edge of Love with her onscreen husband Cillian Murphy, Knightley said: “It was very simple. It was a sex scene and I never like them when they’ve got bras on.”

So when the director asked her to remove her bra, “I said, ‘All right then.’”

But when it came to her singing scenes, the British actress needed much more persuasion. On hearing she had to sing live in front of the cast and 100 extras, she said, “I thought I was going to die. My knees actually started buckling.”
