Shooting digitally would not have been easier. Cameras are the same size. I always shoot on film unless I have a reason not to, which I haven't had yet.

I could only shoot when the subway was on the other platform. Little things like that, and the platform is very narrow. It's not like you can hide if a subway comes so a lot of things happened because of that. Or a thousand people just came and looked straight into the lens like they didn't expect a movie to be shooting.

I think video is very useful, but it's very useful when you want a certain reality.

Now that everyone's shooting digital they want the anamorphic to soften the look. You know, to make it more filmic.

These days in movies you can always come back to a location or do an insert or do something, so that's not even an issue any more. But coming back every day to the same plane, it messes with your head.

Obviously in the close-ups we bring extras around or we do it later, but them running in and the big shots, they don't know. They're just coming out.

Camera's are cheap. It's the lenses that are expensive.
