"I was friends with Brittany Murphy, and the way she viewed herself was always really heartbreaking to me — the things she felt she had to change to be a successful actor. She was perfect just as she was, but people were trying to cast her as, like, 'the fat one,' because when she was a very young teenager, her cheeks were a little bit round. People tell you that you're a particular thing, and it's very hard to fight back against."
