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.

Pick up a camera. Shoot something. No matter how small, no matter how cheesy, no matter whether your friends and your sister star in it. Put your name on it as director. Now you're a director. Everything after that you're just negotiating your budget and your fee.

I guess Titanic because it made the most money. No, I`m kidding. I don`t really have a favorite. Maybe Terminator because that was the film that was the first one back when I was essentially a truck driver.

Any direct experience that I have with indigenous peoples and their plights may feed into the nature of the story I choose to tell. In fact, it almost certainly will.

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.

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.

Every time my cameras go out on a movie, we learn something new and then we take what we learn and we put it into the next generation of the cameras so we're constantly improving. It's kind of like building a race car, racing it, then running back to the shop and working on the engine some more and tinkering with it to improve it.
