I was trying to find out what happened in my lifetime, because I was an older man. We lived through two terms of George Bush, and I was wondering, "Is he an exception to the rule, or he is a continuation? What is driving all these wars? What is driving this attitude of aggressiveness and militarism?" I got my answer - and it was a shocking answer. I found is this whole strain of history, this whole school has been denied by the media. It is a bizarre blindness, because we are such an intelligent country. It's bizarre that we can't get our own history straight.

Bin Laden was completely protected by the oil companies in this country who told [President] Bush not to go after him because it would piss off the Saudis.

You can never judge how the film will be taken; you can only make your best effort, and put out what you feel. How it's read, you never can tell. Or remembered for that matter.

I don't want to make a half-assed film. It's not my area of expertise.

I'm not an activist. I'm a filmmaker. I'm a dramatist. My strength is to tell a story, to find a way to tell a story that makes it exciting. Our Untold History was a huge challenge. Snowden was no piece of cake, because writing code and breaking code is some of the most boring stuff you've ever seen.

Wall Street is a huge issue. And it's controlling our lives today with this so-called election - we really have no choice. We're really just onlookers. The national surveillance state has not been debated by any candidates, Democratic or Republican. Our wars, our repeated wars - our new war in Syria has not been brought up because everyone agrees essentially that we have to continue doing what we're doing. And maybe even now go back to Libya.

I love the act of writing. I like the quiet, internal aspect of it. If I lost track of that, I couldn't direct the same way. I couldn't be a director for-hire; it's just not my nature.
