You've got to protect whatever creative talent you have left.

For me, the key image is the boat coming through the fog at the beginning. It's something I imagined and liked and I guess there are other references in other films I make - the similar type of image. But I think it's interesting, it's breaking through the mystery, or maybe it stays in the fog... we don't really know. Where is he at the beginning of the film, who is he?

If your mother cooks Italian food, why should you go to a restaurant?

We’re face to face with images all the time in a way that we never have been before... Young people need to understand that not all images are there to be consumed like fast food and then forgotten – we need to educate them to understand the difference between moving images that engage their humanity and their intelligence, and moving images that are just selling them something.

In truly great films - the ones that people need to make, the ones that start speaking through them, the ones that keep moving into territory that is more and more unfathomable and uncomfortable - nothing's ever simple or neatly resolved. You're left with a mystery.

I'm very phobic about flying, but I'm also drawn to it.

All I can do is try to do the best work I can. I need to work, I like to work... although I complain about it, but I do like it - and I just need to make the best film I can.
