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.

In my opinion, it's more interesting to see magic happening in a world that feels grounded. If the world is already crazy, then anything can happen. So it's better to start with something real.

If I have a good dream and I wake up happy. When I have an idea, I feel happy. Sometimes achievement and relationships can make me happy. I have a son and to see him grow - he's 22 now - that makes me happy.

I don't thrive on control. I'm not looking for control. I think I get better results when I don't control things.

I'm going to work with Dan Clowes. After Charlie Kaufman, it's hard to fill up the gap. It's hard to find somebody who... A lot of writers, I can clearly see the desire of succeeding before the desire of expressing themselves. Sometimes people get upset when you want to be different. You were talking about "whimsical," which is a nice word. But sometimes they use the word "quirky" in the pejorative sense. I get frustrated, because they feel like I'm doing whatever I want, and there is no ground, and I don't really care. They feel it's cynical. But I don't think I have any cynicism in me.

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.

It's a very American thing that everything has to be a business. Americans think... I like America, or I would not be here. There are great qualities to this country. But this sense that everything has to be a business is sometimes overwhelming.
