Never say never - and I certainly don't judge anyone who does it. But most of the characters I play are going through some kind of emotional turmoil, so my job requires me to have expression. If my face was froze, what right do I have to play that part? All the women who haven't done anything to their faces are still able to play great roles. And some of the ones who have done something have messed it up - they look freakish. Anyway, for me it's about playing women with rich lives - and the longer the life, the deeper the wrinkles.

Who are we when we leave our families? Who do we become? What are we capable of? That's something that never leaves us. It begins at that point in your life when you leave the nest, and I don't think we stop wanting to explore that question.

Rodrigo Garcia is a brilliant writer. He just loves women. It is evident. When you are in the presence of him you can just tell he has a terrific understanding of women. He has two daughters, and he loves his wife.

I'm a tomboy now. I always wanted to fit in with my brother's group, so I climbed trees and played with lead soldiers. But I'm a woman's woman. I never understood women who don't have woman friends.

Sometimes they come to you and it's a small role, so it's about the experience and the journey and mixing with people you know you will learn from. Or sometimes it's a scene in a movie that you think, 'I just have to play this person.'

Since I had children I have taken huge amounts of time off. In a way it's a really good thing, in this show business especially, to have lots of private time, having lots of time to be in the world to observe people and read and take care of my kids helps me to come back into work with a thrill.

I've always loved to dance and keep fit but more recently I feel like I cannot keep up any longer and my back starts to hurt. And I get angry and then I have to really learn to forgive myself and go: you know what, you're nearly twice the age of some of the people in this room, give yourself a break.
