I love the ups and downs and the eccentricities of my career. The worst movies have produced some of the best friendships.

It's funny, when people want things to be very truthful and you're dealing with an inexperienced actor. I'm of the school that believes things like that have to be very carefully choreographed. You need people there to say, "It's going to happen like this."

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.

I was lucky, because Ewan McGregor had already been shooting with Roman Polanski for about a month before I got role. And he did a faultless impersonation of what it was going to be like. So when direction happened, it was like, "Oh yeah. That's what Ewan said was going to happen." And so it was a little bit less debilitating than it might have been.

The excruciating moments of drama are when people are allowed to show or say what they feel.

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."

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."
