The only thing you need to make a film is to not be afraid of anybody or anything. John Cassavetes said that. John was inspiring, but he was also direct. He knew that there was no time to be indecisive, or to worry about whether the decisions you’ve already made were right or wrong, good or bad. I think that for John, there was no such thing as a “mistake”—you can only move forward, you can never move backward, and you can profit from absolutely everything.
Many times in my life, I’ve told the story of John’s advice to me after he saw a cut of Boxcar Bertha, a picture I made for Roger Corman. In essence, what he said to me was: Just concentrate on making the movies you need to make. Of course, many directors have approached this in many different ways—Claude Chabrol, for example, who never stopped working and made many, many movies, personal and impersonal. Even John made pictures like Gloria and Too Late Blues. The point is this: Protect the ones that you need to make, keep them alive for yourself, and then make them.
