As a mother, you feel much more vulnerable. And when you're vulnerable, you're a much better actress.

I think you approach a part the same way and just find out in what's making them tick and who they are. In a movie like this you may have a little less time and few dialogue scenes and exposition scenes for your character to really get that across, and so I wanted to be able to convey that she's not somebody who's just punching a clock but she has this weird emotional investment in her job to where she does get quite myopic and that's what makes her relentless.

I'm attracted to playing things that I find difficult, just because it's a journey that is much more interesting.

At Oxford University, I studied languages so I could read the great novels as they were originally written. I took what in the United States would be a double major in Russian and French, but I have to admit that the pressure of getting through so many books spoiled reading for me.

I do find it extraordinary that men are so prepared to pay for your dinner here. That simply never happens in England. When I first got together with Len, I couldn't understand why it seemed like he was always trying to get into my side of the car. He was holding the door open for me! I don't know what you teach American men in school here, but you have to keep it up, because it's extremely charming.

No one really knows who I am or where I came from in America, and there's something quite nice about that.

If someone had told me years ago that sharing a sense of humour was so vital to partnerships, I could have avoided a lot of sex!
