I generally go into a movie with a very strong vision, with how I want to make the film, how I want to shoot the film, how I want to edit the movie, what I want the sound to sound like. So I have a very concrete idea even if I don't storyboard it, I know exactly what I want to do once I get into the sequence. Now having said that, I try not to let that slave me to the process. So if I do storyboard a sequence I don't necessarily stick to it if I discover more exciting things on set.
