Well, there are three different processes of making a film, of course. They're sort of re-written three times. You write it to start with, and then you shoot it and you re-write it while shooting and you sort of re-write it as you edit.
I'm not really a director for hire. You read these scripts and go, 'This is a really great script, but Paul Greengrass would make this so much better than me.' I usually say, 'I know who would be good for this. It's not me.'
Every now and then I have to teach directing. The thing about the theatre is that the most important thing you can do as a director is to make sure that everybody is in the same world - you have to create the world and make sure everyone buys into it.
The really successful work in England tends to be working-class writers telling working-class stories. The film industry has been slow to wake up to that, for a variety of reasons. It still shocks me how few films are written or made in England about working-class life, given that those are the people who go to movies.
