1. "If you're willing to have the same expectations of yourself that many male actors have and many women actors deny themselves by wanting to look sexy or pretty. Then there are a lot of parts that are open to you. If there's one interesting thing about acting, it's trying to lose your ego in the character."

You can be moved by a performance on set, but when you see it on screen, it does nothing. Yet there will be someone you simply didn't notice on set that on screen: bam!"
