I can't help believing that these things that come from the subconscious mind have a sort of truth to them. It may not be a scientific truth, but it's psychological truth.
I had written in another draft a completely different kind of fight, but they said they couldn't afford to shoot it. They needed a fight scene, though, so I was told to put a fight scene in, but not the one I had written.
Sometimes when I consider what tremendous consequences come from little things, I am tempted to think there are no little things.
