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.

Indian films never show cows. When you go to India, the most noticeable thing is the cows. Everywhere you look, there's cows walking around! Just by introducing the idea of animals - livestock walking around - suddenly makes it more real.
