I loved Rushmore. I loved the script. I mean, that is what drew me to it, just the actual piece of literature the script is. But I never thought in a million years that anyone would see it or respond to it. It was an absolute joy that it was so loved and continues to be. The same with The Sixth Sense. I thought, "No one's going to watch this. Bruce Willis hasn't got a gun. There's no shagging. Lovely story, sweet and profound about loss and death, but no one's going to watch this."

I thought "I've coped with some crazy situations, and I can do this." But working with Roman Polanski is so different from the fashionable and accepted way of directing now.

From a very young age, I wanted to get up on stage whenever I went to the theatre - the actors just seemed to be having so much fun. One of my worries about theatre, in fact, is that the actors are quite often having more fun than the audience.

My parents are both lawyers, and my father always said his best cases have been returns, cases that come into his office from another lawyer. So he said, "Never be ashamed to take a return." All my best roles have happened because someone else dropped out at the last minute, and God bless those actresses for their queeny fits, their sprained ankles, their better job turning up, because that's how I've got my best work.

I didn't know box office was a thing you could possess but I don't have it. I go up for lovely roles and people with this nebulous thing called box office get them so there isn't much I can do about that unless you know where I can get some box-office myself!

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.

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.
