I think the reason why strong women have such a powerful impact is that you've got the strength of a man with the heart and sensitivity of a woman.

There are no captions on red-carpet photos that say, 'This girl trained for two weeks, she went on a juice diet, she has a professional hair and makeup person, and this dress was made for her.' I just wish they'd say, 'It ain't the truth.'

My dad took me for an audition once, to show me, 'OK, you want to be a child actor, this is what it's like.' I sang a folk song about donkeys on this West End stage with this big director, and there was a queue of 200 girls all singing 'Memory.' I was terrible. Terrible.
