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.

T.S. Eliot, who learned to swim at the same beach as I did, just threw in the towel and moved to Cheyne Walk. I'm not going to do that but I'm not scared of the open channel between me and Britain.

If I can give a young author any advice, whatsoever, never let anyone announce the film sale of your first novel. Film rights are sold to almost every novel, but it shouldn't be the lead story in your first engagement with the press. Then you end up getting reviews like "a novel made for the screen" and things like that.

I'd been working so hard making the film that I hadn't even emotionally processed the fact that I was a director.

If you decide to do Hamlet in a funny hat staged in a ruined factory, it doesn't make you Shakespeare.

I learned from Ridley [Scott] how to come out of the trailer at a fast walk and make your decisions and keep it going. We were very much on time and under budget, as they say. That was a very important thing for me and very satisfactory.

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.
