When I had dark hair I definitely felt that I was more anonymous.

It is a huge amount of pressure playing someone like Valerie Plame-Wilson. First of all who she is and what she's done is wildly intimidating and impressive. It is just scary to take on that responsibility, and you want to honor her story, an incredible story that affected us all. She is often doing things that were confusing to me, like her sexual prowess. I think that she is in a lot of pain and she has been really badly wounded along the way. She doesn't hold men in the highest regard... not just men but people.

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.

I was never completely destitute. I think I borrowed money once off a friend, but I've always been quite careful with my money, having come from not much of it.

In your 20s - and these are generalizations of course - I feel like I didn't care about as many things or as many people, or even myself, as much. There's more recklessness and more ruthlessness; you're not as considerate of how things land with other people I think.

I don't think of myself as a terribly confident person. But I have a survival mechanism that was instilled in me by my mother.

It seems like a lot when you have three movies back to back but that's not really how it is.
