I'm not much of a Method actress, so even though my character in The Ghost Writer was quite dark and bad-tempered, I could only do that if I was seeming quite perky.

It was as big as a Beatles concert, I guess. Friends was unbelievably popular in Britain, and it was incredibly exciting. I had never experienced anything quite like that before in my life. I was honored to be a part of that.

I am a pathetic and gushing Nick Hornby fan, and I wanted to be in High Fidelity, and I wanted to be in About A Boy, and those two directors - one who's a dear friend, and one who has never cast me in anything, despite my pleading... So there was another Nick Hornby script going around being cast by a friend of mine, and she said, "There's a very small role in it, but you'd be right for it." I was like "I don't care how small, I'm going to be in this Nick Hornby film."

I hope I never get in the situation where I refuse to audition, because I think people have a right to see you interpreting the character, and if you don't do it the way they want you to, they have a right to say, "No."

Carey Mulligan is completely self-possessed. She knows what she's doing, and again, quite like the big-hitters I was talking about, my job was just to feel and reflect back the amazing performance coming my way. If anything, I was slightly pathetically flying in her tailwind. She's an extraordinary actress.

I'm a mixture of Anglo-Saxon, a bit of Spanish and one-eighth American. I've often wondered if I have an Asiatic ancestor from the East as well because I have deep-set eyes. Make-up artists are constantly trying to shade my eyelids, and I have to point out that I don't have any!

My parents taught me everything and set me up for life. I owe to them all the things I'm passionate about: music, art, the people I love, my career and family life, the fact that I have children and the way that I raise them.
