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.

The thing that I love about acting is the fact that I can help people feel things, know themselves or feel less alone. It's my form of expression, in the same way that someone might paint a picture or sing a song in that you're hoping that it moves somebody outside of their own way of thinking.

I consider myself British and have very happy memories of the UK. I spent the first 14 years of my life in England and never wanted to leave. When I was in Australia I went back to England a lot.

If I have to produce movies, direct movies, whatever to change the way Hollywood treats older women, I'll do it. If I have to bend the rules, I will. If I have to break them, I will.

I'm not happy unless I've got a little bit of fear going.

I don't know that any woman could ever not think about that at some point - even making the choice not to do it and getting to the place of peace of choosing not to be a parent, there would have still been some struggle in between. I'm not a man but I don't think it would occupy their minds as much.

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.'
