That's what it really gets down to. The technology is in service of the story, yet we love the medium so much that the story is inspired by the technology. So we rethink it a little bit and try to come up with something that is doable. That's really the responsibility I have as the director. All I need for the story is this.
Computer programming is a very exacting process.
It doesn't work. Therefore, at times they tend to take things very literally, to make things absolutely perfect. Part of my job is to say, that's good enough. You don't need to make every little teeny thing in the whole movie as detailed as it can possibly be. It's too far away, or it's off in the bottom of the frame, or we whiz by it.
