Ridley Scott

For 'Prometheus,' I came back to a very simple question that haunted me that appears in the first 'Alien,' and no one answered in subsequent Alien films: who was the 'Space Jockey' - the big guy in the seat? If you really go into that, it becomes the basis for a pretty interesting story.

I'm agnostic because I went through the usual process of parents insisting you go to church, and yet they didn't. So there's me, sitting in the chairs, thinking, 'Jeez, why am I here? I'd rather be playing tennis, seriously.'

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.
