Get the right actor, and the job's halfway done. I've only miscast major people twice in my life – out of respect to them, I won't tell you who. After a couple of days' shooting, I had to tell them I was letting them go. It was hideous.
Music is the fountainhead: everything comes from that. At the moment, I'm getting intoxicated on Beethoven, and I use Pink Floyd for inspiration while making a film. Their music contains a sound for almost everything I do.
When you get a cut and think, 'I'm going to make a halfway decent film.
The feeling that maybe you won't ever get your inspiration back. That's a very cold place to be.
Movies tie things up in an arbitrary length of time, but I have always liked things that aren't fully realised.
