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.

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.

Broken Horses is an artistic triumph. Beautifully written, acted and imaged, this film wraps slowly around you like a king snake and squeezes.

I'm certainly not a fan of conversion when you could shoot the movie in 3-D.

I don’t feel that I’m making movies for iPhones. If someone wants to watch it on an iPhone, I’m not going to stop them, especially if they’re paying for it, but I don’t recommend it. I think it’s dumb, when you have characters that are so small in the frame that they’re not visible. I’m trying to make an epic.

Go home, pick up your video camera, and make a film.

Nature's not our enemy, it's our sustenance; and we need it - and we need nature healthy for us to be healthy and to survive long term
