Long, long before I became a filmmaker I was talking to killers. Filmmaking was an after thought.

I actually felt diminished by watching [Donald Trump's]. If this is what discourse has become in America, who even wants to know about it? It's just too demoralizing and unsettling.

The chance that any given sentence is a lie, rather than a truth, I think, is fairly great. An intentional lie, a self-deception, a misconception - there are lots of categories of untruth, not one grab bag. And hotographs can reveal something to us, and they can also conceal things.

Forty years ago this country went down a rabbit hole in Vietnam and millions died. I fear we're going down a rabbit hole once again - and if people can stop and think and reflect on some of the ideas and issues in this movie, perhaps I've done some damn good here!

Mike Wallace's interviews may make great television, but they don't produce great evidence.

I've always wondered where explanations end and excuses begin.

I remember on page one of The New York Times the article about Fred Leuchter. The heading was "Can Capital Punishment Be Humane" and it was the story about an electric chair repairman and execution machine designer. And then buried in the back of the paper was the fact that Fred Leuchter had also been involved in holocaust denial.
