I'm fascinated by what makes up a self, how one becomes a self, how much is it an answer to others and how much is it an essence of self. We learn how to be people from other people. Then you think - what's personal freedom? Is self-creation possible? This book is dedicated to a friend of mine who really did re-create herself. I didn't do that - I stayed in the circus and am a circus performer like my parents were. I did what I was raised to do - I'm glad I did but I'm fascinated by the people who managed to do something else. I was always very curious about other people.

I do think it is a kind of illness in the sense that it sets you apart, it injects you with an endless, unslakable thirst to keep making the thing. The artist has to voluntarily use themselves endlessly.

I think one of the great joys of being a writer is you can transcend everything, even your own sex, what century you live in, and how you think. I found it quite natural to think as a male because I actually think that as a female, one often thinks in the mind of a male in terms of eroticism. You think about what the other person feels. So it's not that hard to imagine being that person.

I had a lot of great lakes of ignorance that I was up against, I would write what I knew in almost like islands that were rising up out of the oceans. Then I would take time off and read, sometimes for months, then I would write more of what I knew, and saw what I could see, as much as the story as I could see. And then at a certain point I had to write out what I thought was the plot because it was so hard to keep it all together in my head. And then I started to write in a more linear way.

I have a great drive to make things and sometimes I forget to slow down a little.

You work with each individual actor as you perceive their needs to be. It's something that you've figured out in the weeks of pre-production.

When I left university I was sure that I was going to be a painter. Then I had a crisis, a revelation. I saw Dolce Vita and my mind was blown by it, by the synthesis. I realised I wanted to be a filmmaker and started making films. I was writing screenplays and couldn't get money because my work was so uncommercial. I got married and started writing fiction. What was wonderful is that it gave me my freedom because no-one can tell me I can't work. Novels have become equally important to me as films. I consider myself a storyteller and passionately engaged in both of those disciplines.
