For me, the most important word in cinema is the word freedom. For example, in Europe, we've got freedom, we've got the final cut and that's something which is marvellous.

It's always more interesting and more difficult to make something positive than negative. To be negative is very easy.

In the States, I learned to fight for every idea. Sometimes, a director has to be a tyrant to keep the quality.

I think of a film as being like a toy train.

I'm very slow, and I do everything myself. I remember I spent three days to change the size of something I had sketched because I felt it was too small.

When I was a child, I had a ViewMaster, those red box glasses with little discs, so that you can see 3D images. They were my first steps in cinema. I was eight years old, I would cut and change the order of the images and that's how I created films that subsequently I recorded and projected and showed my friends. So I already took my first steps in 3D when I was eight years old.

If you make the right choice in casting, your work is nearly done already. You don't have to spend a lot of time directing the actors, because they're so well suited to the parts.
