It's been very much in the blood since I started imagining films or shooting with 8mm when I was a kid. I made some films and thought about films, but then I went into writing. Becket is something that's definitely on the cards. We have to see where that fits in the schedule, because it's a big picture and I have a lot of writing obligations at the moment. I'm wary of anything with a budget over a certain amount.

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.

I need as much of the business of making a film to be in my own workspace. It really ought to be a bit more like doing a novel, alone, at first. I'm feeling my way.

If you need someone to come out of the sewer with a wire you don't hire someone who needs laborious collective instruction. You let someone do his job, whether he's a focus puller or a surgeon.

The thing about The Departed, the x-factor that people can't quite put their finger on, is that it deals clearly with class and accent all these things that are fundamental to Boston, but previously anomalous or even prohibited in demotic American films.

My gratitude to Ridley [Scott] isn't anything new. I named one of my kids after him. But he's a very important person to me.

I love audiences, but they're not there to drive the bus. Whenever you ask opinions or anticipate opinions you can get pretty terrible art, or non-art. You need a single guiding intelligence, even in a collaborative form.
