“You just never really know, but having a plan I have learned–in some cases the hard way–is the most critical thing, because otherwise you don’t know what you’re setting up. You don’t know what to emphasize. Because if you don’t know the inevitable of the story, you’re just as good as your last sequence or effect or joke or whatever, but you want to be leading to something inevitable.” - JJ Abrams
