I think that the whole voyeuristic attitude of filmmakers or of me personally - of shooting documentaries and so forth - is an important issue.

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.

Not one Wall Street executive has been charged with crimes since the 2008 financial crash.

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.

We, as film-makers, are privileged. We can make people cry or laugh. We can make them think and feel. It is a great privilege and a great responsibility.

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.
