I really needed to have something in my life, because I realized there were other things more important than my career. So I love having my children and my family.

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.

There are movies where I've walked onto the set and felt, "This is home," and I'm confident in myself and my work, but that was my first experience of live TV. At that stage, Friends was at its unassailable height of popularity and brilliance.

Ewan McGregor and I said this to each other after we saw The Ghost Writer. Every time Roman Polanski did a "No, no, no!," he was right. It was really as if a sculptor was asked to sculpt the embodiment of despair - that was the attitude he would strike. But as with every sort of inspiring teacher you ever had who was strict and scary, when you get it right, the sun comes out, and it's worth it.

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

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 analysis of the situation was that Roman Polanski wasn't trying to break us down or get a performance out of us by destroying us. He was absolutely, very simply, trying to recreate this clear picture in his head. And the pictures he creates are absolutely perfect, and they are exactly what he saw in his head.
