My grandfather lived across the garden from us, and in his attic he had a lot of radios, appliances and inventions that he had made over 50 years, such as a keyboard called a clavioline, which can be heard on some Beatles songs - it was popular in the 60s. So we had all that at home.

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.

It's very hard to say I'm surrealist. It's like saying I'm poetic. It's not something you want necessarily to be aware of.

Every movie I do is challenging for me. There is some element of imaginative that you wouldn't have in a typical movie.

People always say there is competition in nature, but I think that because we are human, it's not only competition. Because we are human we have something other than competition - sharing, helping others, or being oneself. Competition is really kind of ugly.

I find, surprisingly, that actors are liberated in their work if there's stuff going on around them, because they can't think too much about who they're supposed to be.

I've always liked the idea of inventing stuff. My father told me, because I was naïve, I would think things could work and therefore do them, because I would have no doubt even though there was no solid foundation for this confidence. I don't think I would be a real inventor. But when I set out to do animation, which was my first step into film-making, I realised I could achieve this idea. I could take some elements, create a sort of clumsy invention, and make them work for the camera.
