If John Cassavetes, my friend and mentor, were alive today, he would certainly be using all the equipment that’s available. But he would be saying the same things he always said – you have to be absolutely dedicated to the work, you have to give everything of yourself, and you have to protect the spark of connection that drove you to make the picture in the first place. You have to protect it with your life. In the past, because making movies was so expensive, we had to protect against exhaustion and compromise. In the future, you’ll have to steel yourself against something else: the temptation to go with the flow, and allow the movie to drift and float away.
