Scaring someone's the hardest thing to do, and that's why most of scary movies are not scary. They're sick, but not scary. There's a lot of sickness out there, of people who then sit there and watch it, which I think is absolutely dismaying.

I think going into space would be like going deep into the ocean, like 5,000 meters down. When you go down that far, it's just awfully black. There's not much there except mud and some particles. I imagine space would be a similar thing. The only difference is you're hoping to bump into some sort of intelligent extraterritorial being.

I'm a moviemaker, not a documentarian. I try to hit the truth.

It goes back a long way. I wanted to make Tristan + Isolde as my second movie. My first movie was The Duellists. And I was standing in a very romantic part of France looking around me thinking, "My God, this would be perfect for Tristan," and to cut a long story short it never happened because I did Alien instead.

I think if I'm going to do a science fiction, I'm going to go down a new path that I want to do.

As I'm getting older, I want to make sure every film I do really counts.

Some people like to do everything always the same thing. That's another way: To do the same thing.
