I want to play interesting women.

I was advised by an American agent when I was about 19 to change my surname.

As Ralph's character begins to discover the political thriller aspect of the film, he falls deeper in love with his wife, so the two run together. That's the beauty of this film. It has fast pace and excitement, but it also has heart and soul.

Film is such a director's medium; you're really in their hands in terms of the real storytelling. As an actor, you can give a performance moment to moment and some of your takes will be used and some of them won't. I think there are great films you can make with bad performances, and vice versa. There are all combinations of those things. It's really down to the director what happens, I think, so that's why it's really good to work with very talented, bold directors.

I don't judge the character at all. It's a bit like being someone's defense lawyer - you have to believe in their innocence in order to defend them.

I love the international feeling In New Yokk. Different foods. Different people. There's everything here. Museums, theatre, there's so much to do I feel guilty about not doing too many things.

People believe in you more after you've won an Oscar, but it's up to you what choices you make.
