Right now, we live in bad times in this country, and the fact that there are filmmakers addressing political and social issues is to me a good thing.

When you start talking about the known knowns and the unknown unknowns, you're thrown into a crazy meta-level discussion. Do I know what I know, do I know what I don't know, do I know what I don't know I don't know. It becomes a strange, Lewis Carroll - like nursery rhyme.

Finding truth involves some kind of activity. As I like to point out, truth isn't handed to you on a platter. It's not something that you get at a cafeteria, where they just put it on your plate. It's a search, a quest, an investigation, a continual process of looking at and looking for evidence, trying to figure out what the evidence means.

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!

The fact that the world is utterly insane makes it tolerable.

Ecstatic absurdity: it's the confrontation with meaninglessness.

I used to work as a private detective years and years ago. And my boss gave me this one very simple piece of advice about trying to figure out who to interview first in any investigation. His recommendation: Always pick the people who were fired. Pick the people who are pissed off.
