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.

The power of sound to put an audience in a certain psychological state is vastly undervalued. And the more you know about music and harmony, the more you can do with that.

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.

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