Casting is all about availability, as much as anything else.

For me, film has been good because I'm able to work at top crack, working at something I love to do, in the only literary form in which you can still make money. There are no famous novelists, not as novelists used to be famous.

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.

I don't think the latest Star Wars pictures have any artistic intentions, but the original picture opened up epic science fiction.

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.

It's interesting to think that my children know more about the process than many mature critics.

The first time I ever thought about doing a film seriously, I was in London. I was about 17 years old. I was just standing in the street, a bit dazzled by an Antonioni bus wipe, which by the way are inherent in London, and I imagined a film set in London starting out with the riff from The Yardbird's "Heart Full of Soul", and now, how ever many years later, I've done it.
