There is an amount of abstraction in my movies, and sometimes they don't really understand it until the film is finished.

The problem is, with a lot of children's films, they are very commercial.

The first dolly track was somebody who had the idea to put the camera on a boat on a canal. So the boat would move very slowly but steadily. So they would see all that surrounds you and you'd see the landscape changing slowly. So that was the first time.

I like to use a bit of chaos when I shoot. I think it may be something from the way I shot my first film - I was very scared, of course, and I prepared everything, I wanted to make sure that the characters did the right thing at the right time on the storyboard. But then I realised that in life, there is so much more than what you can predict or write in advance, that when you shoot the story, it's good to leave some gaps where you lose control. I think this combination of chaos and organisation gives a kind of quality.

I'm not judging the films. People make these connections through a film, or because they know them. But the fact that they erase them and have to start from scratch, I think that's an important point. A lot of kids, when they have a camera, have tended to do remakes of existing films. You have a lot of kids that make Star Wars. And I think that's creativity, but not as much creativity as starting from scratch.

I think some people feel that if you are going to have 3D, then you have to shoot in 3D, but they shoot 3D, so of course they're going to say 'my way of doing a film is better.' I'm not telling anyone how they should do their film, so why should anyone tell me how I should do mine?

The problem when you edit a film together, when you shoot a film, you are drawn into the moment. You want each moment to be special and full of life.
