If you wait until the right time to have a child you'll die childless, and I think film making is very much the same thing. You just have to take the plunge and just start shooting something even if it's bad.

Literary science fiction is a very, very narrow band of the publishing business. I love science fiction in more of a pop-culture sense. And by the way, the line between science fiction and reality has blurred a lot in my life doing deep ocean expeditions and working on actual space projects and so on. So I tend to be more fascinated by the reality of the science-fiction world in which we live.

I like the evening in India, the one magic moment when the sun balances on the rim of the world, and the hush descends, and ten thousand civil servants drift homeward on a river of bicycles, brooding on the Lord Krishna and the cost of living.

What are the lessons learned? Well, I think number one is curiosity. It's the most powerful thing you own. Imagination is a force that can actually manifest a reality. And the respect of your team is more important than all the laurels in the world.

Religions fulfill deep-seated psychological needs for people, and if you don't get it from a specific religious doctrine, you'll get it from the kind of films I like to make. A film like The Terminator is consciously meant to give a sense of empowerment to the individual.

Jack: Rose! You're so stupid. Why did you do that, huh? You're so stupid, Rose. Why did you do that? Why? Rose: You jump, I jump, right? Jack: Right. Rose: Oh God! I couldn't go. I couldn't go, Jack. Jack: It's all right. We'll think of something. Rose: At least I'm with you.

Don't get seduced by your own stuff. Don't get high on your own supply. The hardest thing as a filmmaker is when you're watching a film that you've worked on for several years. You know every frame so intimately that holding lots of the objectivity of a new viewer who has just seen it for the first time is the hardest thing. Every aesthetic decision you make - and you make thousands of them every day, have to - in theory, must be done from you being a blank slate. You almost have to run a program, like a mind wipe, every time you watch the movie.
