Getting the audience to cry for the Terminator at the end of T2, for me that was the whole purpose of making that film. If you can get the audience to feel emotion for a character that in the previous film you despised utterly and were terrified by, then that's a cinematic arc.

I don't look at scripts. I just write them.

Your only competitors are your past achievements.

You don't rest well as long as you're seeking vengeance. I feel sad justice wasn't done, but it's time to move on and sleep well.

I tried [being a mogul]. It bores me. I don't really want to produce other people's movies. Because they're either grown-up filmmakers like Steven Soderbergh or Kathryn Bigelow that didn't really need me - and I've produced both of them. It's fun to sit around with them and be collegial, but they don't need me. They can make the film without me. I make my own stuff. There are tons and tons of other things I'm interested in that have nothing to do with movies or are documentary projects.

Writing a screenplay, for me, is like juggling. It's like, how many balls can you get in the air at once? All those ideas have to float out there to a certain point, and then they'll crystallize into a pattern.

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.
