Sometimes you see films, not just science fiction films, where you get the sense that if the camera were to pan just to the left or the right, all of a sudden you'd be seeing light stands and crew standing around. But with 'Blade Runner,' the beauty of it is that it felt like a real, breathing city.
Basically, if you want to have a computer system that could pass the Turing test, it as a machine is going to have to be able to self-reference and use its own experience and the sense data that it's taking in to basically create its own understanding of the world and use that as a reference point for all new sense data that's coming in to it.
My job is really to... everyone is reading the script, and my job is to make sure we all interpret it in as much the same way as possible. And then I give them the freedom to sort of - to get their performance across and then make suggestions where things are not working and accentuate and push things where they really are working.
Film directing is really undermined if you attempt to do it by committee because there has to be a single vision as to how to tell a story. It's like if you were at a campfire, and everyone is taking turns to give one sentence in telling a horror story. It would be a mess - it's not going to make sense.
