I sometimes shy away because I don't want to be too 'showy-offy' but the older I get I think, 'You have a handkerchief, put it in your pocket.'

When someone like Steven Soderbergh asks you to do a film you know you're in good hands. You know it's going to be slick, and it's going to be intelligent, and it's going to have a kind of style to it, and I would probably have done anything to be really honest.

If you want to change who you are, you have to change what you do.

When you got source material, whether it's a play or a book - a great writer often appreciates being adapted and developed. It's like when you go see a production of a great play and they are always different. There is always room for interpretation.

I've always thought Prince Charming in Cinderella was the most boring role; I'd rather be the Wicked Witch.

My only obligation is to keep myself and other people guessing.

When I think about it like that, it feels like a burden. But that won't mean I'll be single for the rest of my life - I hope. I feel very settled with myself in my world. I don't feel as needy and desperate to prove things about myself. In my twenties I was very keen to achieve this and disprove this and that. Now I enjoy just being able to concentrate on my children and my work and myself.
