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

The smarter people I know declined to watch the most recent debate [with Donald Trump].

The way I go about making a movie... even the ones that are interview-driven, I go into them not knowing what's going to happen, and feeling my way through.

I'm really interested in self-deception. Really interested in how people live in bubble universes. How people can fail to see the seemingly obvious.

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.

A lot of the distinctions that we make between drama and documentary are spurious. We're deeply confused about these issues. About the difference between the two, about where documentary ends and drama begins.

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.
