I guess maybe I was hired to play in the Doll House because of my dinner scene in The Sixth Sense, which has been scrutinized a thousand times as to whether you know Bruce Willis is dead, or whether I'm talking to myself. I think that maybe if that could be my forte, to do a scene and be able to say it could be read this way or that way.

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."

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.

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

Ewan McGregor is a very genial and entertaining man, and Pierce Brosnan is possibly the nicest man in the world. Actually, it was quite a genial set The Ghost Writer, but the weather and the colors and the actual surroundings were oppressive. But it was a created atmosphere. What was so striking is that Roman Polanski had his crew from The Pianist, and we were shooting in Berlin, so there were German and Polish and French people, and I was just sort of enjoying being in this mix of people, all kind of rubbing along together. That felt good.

If the role is right and it's another situation of having a benevolent genius at the head of it, someone who likes actors, and will protect the actors from the ravages of reality-TV drama. It's a brutal world, and you need to have a strong creative team who can stand up to the network.

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.
