VIDEO: Sienna Miller Turned Down Broadway Role Due to Co-Star's Higher Pay: 'It Would Have Felt Undignified'

Sienna Miller stopped by ABC's GOOD MORNING AMERICA to talk about her new film BURNT in which she stars opposite Bradley Cooper. During the interview, the actress discussed the current debate of unequal pay for male and female actresses in Hollywood and shared a recent situation that she had experienced on Broadway.

"It was a situation where there were two people in a play and I was offered less than half of what the male was offered and I was pretty set that if that was two men that wouldn't have happened." She adds, "It would have felt undignified for me." Watch the appearance below!

Most recently, Sienna Miller played the role of Sally Bowles in the Broadway revival of CABARET, at Studio 54.

In mid-2015, Miller began filming Ben Affleck's 1930s gangster drama Live by Night. On January 7, 2015, it was announced that Miller would assume the role of Sally Bowles in the Studio 54 Broadway revival of Cabaret.
