I might have a guitar or a piano on set to play something for the actors.

I've held onto little musical sketches that I thought could be useful, and the more time that I spend doing them for each film, then the more I have to draw on.

I play piano and trumpet. I studied classical guitar.

There's nothing quite like the idea of failing spectacularly to excite a film maker

I made my first film on 16mm. Then I began using 35mm.Then I began working in Hollywood. And I began to really understand how films were made by professionals. I have to say I wasn't very impressed.

In discussing the process with the actors, I made it clear to them that they could improvise but that the sum total of their improvisation needed to impart certain plot points, and schematic material.

I started using film as part of live theatre performance - what used to be called performance art - and I became intrigued by film.
