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.

When The Sixth Sense was the No. 1 movie in America, I had a Canadian boyfriend whose only assets at the time were a guitar and a van. I don't know what I was thinking.

Family holidays and weekends are really brightly colored memories, full of my mother and father, rather than our nannies and au pairs.

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.

Roman Polanski actually said as much to me once. He had his head in his hands, and I said, "Roman, I've got to tell you, as an actor, seeing the director with his head in his hands... Look, I really want to do what you want me to do." And he went away and he came back, having obviously thought about what I said. And he said, "When my head is in my hands, I'm closing my eyes and trying to remember what I saw in my head, before any of the stuff."

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!

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.
