There was no actually stock footage in "Medium Cool." I wrote the script. I wrote the riots. And I integrated the actors in the film in the park during the demonstrations. But nowhere was it like we had stock footage and then later, in editing, integrated it into the film. It was all done at the time.

When I started, we had just the camera and the person, mostly. And if you wanted to do a dolly shot, particularly working in Chicago where I began, you'd get in the back trunk of a car, and you'd have a friend drive the car, or you'd get in some kid's little wagon that he plays with and have someone pull that for dolly shots.

Most people, I believe, when they're asked profound questions about their own persona are not really able to enunciate it, because it's a combination of so many things.

I've been in wars and in riots and hung out of many helicopters in the early days. And there's a detachment that happens when you look through the camera. You're looking for the shot.

I used it in a shot where Richard Burton goes down the hall to get a gun in a closet. And I wanted to get some excitement, and the hallway was too narrow for the dollies that they had at that time. So it was quite useful.

The helicopter was a U.S. Navy helicopter. There were no civilian helicopters available to film companies, so they just made some stuff out of two-by-four wood. And I would straddle a two-by-four out from the helicopter with a camera and what we call a high hat, which is a low metal stand.

I had a rope around my waist, and the rope was attached into the helicopter in case I fell off. And the shot was a shot that began with Kim Novak going out of a house and getting into a bus. Then it was supposed to go over the countryside and find a freight train on which Bill Holden was standing. And then after seeing a good look at the freight train, the camera was supposed to move up into the sky for the end credits.
