By the time I came to do the final ones [Harry Potter's film], I was working on something that was massively successful. There was a huge difference in indulgence and all sorts of stuff. A very big difference in peoples' attitudes. They were very pleased with themselves. In human terms, it was quite interesting to see the difference.

We're all far too afraid of being so arrogant to say "Either you can or you can't."

My fathers a clergyman, and he was in the mission field for a certain amount of time in British Honduras, which is now Belize.

I've spent a great deal of my life doing independent film, and that is partly because the subject matter interests me and partly because that is the basis of the film industry. That's where the film-makers come from, it's where they start and sometimes its where they should have stayed.

I loved working with [ Lars Von Trier], but I've done two films before, so I was quite used to him.He's a man of incredible moods of course, but he's also a hugely perceptive man, and there's no getting away from that. And he's able to put that perception into something like film, so we're very lucky.

We all have our limitations.

I wanted to work with those boys (producers Andy and Larry Wachowski) because they're so eccentric and peculiar. Larry, of course, is halfway towards being a woman now. It's a crazy world.
