Actors are players and if they're hot, or onto something, you let them go, or you and the actor can both get on to something. I always run out with lines as I think of them.

I've got things I have to do in fiction to sort of register my existence, before I kick the bucket, but it will never be my living and I know it. Plus it never moved fast enough for me and lacked cut and thrust. I need to be in the real show.

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.

I can work in London. A British journalist asked me if I had any trouble working with an English crew, as an American, and I said I might have if I was from Scotland, but I'm from Massachusetts, which is sort of Oxfordshire, but more intellectual. That's kind of unforgivable but you've got to let them have it.

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.

Whatever you cut when there's no deadline isn't really a cut. You're just pushing colors around.

I don't move until an actor is happy, but it was very important to me as a so-called "first time director" to keep the machine moving. It was especially important to me to keep it moving and not be some kind of precious writer-director.
