I felt an enormous responsibility because internationally there's a real passion among kiddies for these books.

It is. I mean people probably know it better than me if you have read the books. I mean, I had not read the third book, by the time I came to do it.

Everybody knows someone like that: wonderful, attractive people full of passion and ideals. You envy them, but you know there's a dark side, which is brutal and cruel and violent. That dark side informs what's wonderful about them, and the passion and rage inform the darkness; they're inseparable.

'Naked' kind of kicked me off into the film world. It just so happens that all of the things that I have been offered have been films, and I've enjoyed the travel that goes along with that.

I could, of course, have written about the film world and the jealousy there and the frequent belief that others don't have talent. But, for some reason, it just struck me to write about art.

It's certainly not easy having to spend a lot of time apart, and having a five-year-old child who's got to be at school. So we need to learn how to organize our time really well because for months we will be in two different countries.
