The changes are part of my writing process. When I write, I imagine scenes. I write things down. I take photographs. I do some casting. I rewrite. It's a permanent making or remaking.

I always write three or four projects at the same time. They're stories that I want to tell, and usually I dump them unfinished for the next one in order not to get too cornered and depressed about it.

When I watch my early documentaries, they're very eclectic. They don't follow any particular [pattern]. I would have gotten thrown out of film school because I didn't. I was just putting them together somehow as the spirit moved me, following my nose, thinking I was brilliant.

For me, each film, each script is like a little journey in itself, and I'm reinventing the wheel. It's like how do I make this film. That's part of the pleasure and that's why I'm not a normal professional director.

I usually make films about what's on my mind at any given time.

I'm a pretty chaotic person, but I'm also a perfectionist. It's a very unfortunate mix.

I have this theory that if you do a film, those who have not fallen asleep or left the cinema, they will live with the film much longer, and it will really enter their imagination and the subconscious much more profoundly.
