The trouble with audition process is, when you're an unemployed actor, it's the only time you get to act, and it can be quite fun. If you feel in control of the material and you feel that the people are pleased to see you and are excited by you auditioning for them, it can be a really rewarding process. But it can also be a very humiliating process.

The best Christmas present I got from my husband was a week to do whatever I wanted.

When the Hollywood thing happened, I thought at some point I'd get to the front of the queue: 'Yes, hello, I'd like to play that role.' But you don't. You just join a different queue.

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 don't tend to spend the whole day in the personality of the person I'm playing.

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.

My very first friend was my stand-in, who's a very dear friend to this day, and she kind of saved my ass. She told me where to stand and where the camera was and where to look. I thought, "If I don't enjoy this, then there's absolutely no point in being an actor."
