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.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
