When I make a film, I never stop uncovering mysteries, making discoveries. When I'm writing, filming, editing, even doing promotional work, I discover new things about the film, about myself, and about others. That is what I'm subconsciously looking for when shooting a film: to glimpse the enigmas of life, even if I don't resolve them, but at least to uncover them. Cinema is curiosity in the most intense meaning of the word.
When I'm editing, I tend to cut, go back over it, cut, go back over it, cut, so by the time I'm done, even with a cut, I don't have a rough cut and then work on it so much. I have a pretty rigorous cut of the movie that's usually in the range of what the final movie is going to be. It doesn't mean I don't work on it a lot after that, but I get it into a shape so I feel I can really tell what it needs, or at least it's ready to show people.
The relationship with actor and director is probably closer to theater, in that, when we record the dialogue, there is very little in the way of the creative collaboration - no cameras, lighting or even locations. Then, once we record, the post process is very similar to the post flow in filmmaking - editing, sound design, mixing, etc. At the end of the day, it's all about storytelling and honing in on a tone by developing a rhythm and structure that suits the storytelling.
