When you go out to shoot a film with all these people it's physically very demanding. It's almost like you're going through a marble quarry and you're carving a big chunk off the side of the hill, hoisting it down and taking it back. Then when you are in the editing room, you start sculpting it and you might have thought it was a horse, but it turns out to be a moose.

The editing really becomes a way of letting the materials speak to you, telling you "this is what I want to be." When you impose your preconceived ideas rigorously on the material, then it tends to object.
