In a funny way, the stories keep themselves alive by emerging from one another. I like that.

I've had stuff of mine adapted by other people, so I've come to the conclusion that a movie is a different form from a novel and there is no such thing as a true adaptation. You have to adapt to this other thing and do it right. But that voice of the original should somehow still be there, and the original intent should still be there. So if the original writer saw the movie, the writer would say, "Well, that's not what I wrote, but that's what I meant." And if you can do that, I think you've done your job as a screenwriter.

If you leave me here," the guy on the floor said, "he'll kill me tomorrow morning." Parker looked at him. "So you've still got tonight," he said.

Science fiction is a weird category, because it's the only area of fiction I can think of where the story is not of primary importance. Science fiction tends to be more about the science, or the invention of the fantasy world, or the political allegory. When I left science fiction, I said "They're more interested in planets, and I'm interested in people."

If you think of movie studio executives, say, as society, then I root for the independent producers.

I don't think I ever have trouble with writer's block. It's different when you make it up as you go - that means you're going to get stuck. I wouldn't call it writer's block, I'd say, "I don't know where the hell this story is going."

I have no known marketable skills.
