The thing about movies is if somebody has an idea that works, it's in, and I say that as a screenwriter as well as a director.

If you change a location opportunistically, to gain a day on the schedule, which I did more than once, you have to re-rig everything creatively on the spot, and you not only have to be able to do that, but do it with great fluency to keep moving. I used to go apeshit when anything got changed in a film but you live and learn, and I have learned.

I'm usually the first guy to propose a change because I'm continuing my process. We're in a context, in this business, a context in which most screenplays work on a very modest level of achievement, in that a lot of them aren't really written by what you would call writers.

All of a sudden I pulled up short and harked back to Ridley [Scott] holding up the script in Manhattan, at the St. Regis breakfast room, and saying, "It's very visual, isn't it," and realized it was the key to my whole life since then.

The novel may be dead as a commercial form. When art forms things die as commercial forms, something happens to the practice of those arts that isn't very pleasant. It used to be that a poet like Tennyson could keep his house and his coach-and-four and his staff of six servants on the income from poetry. That doesn't happen anymore.

Martin [Campbell] is very energetic and precise. He'll on the set like four hours early with a flashlight and I thought, well, I'll certainly try to be very neat about my script like Martin, which I wasn't, but I'm not going to do that bit with the 4AM and the flashlight. I'd love to be able to say I was nervous, but I wasn't. The only time I ever had anxiety it turned out to be asthma.

If you write a screenplay that gets circulated, you have a bigger readership than any literary novelist. And it's an educated audience as well.
