It was 100 feet of 16 mm black-and-white film of a car coming to a stop sign, and driving off. I had to decide how to frame and light it. It was magic. There was a sense of mystery.
I worked also, doing things such as our paper route and, later on, waitressing.
So when I was told to work, ten, twelve hours a day as an assistant pro, I didn't complain. It was normal.
