My protest against digital has been me saying, "What's going to happen to film?" The result is that Kodak is out of business. That's a national tragedy. We've got to keep making film.

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.

Hell is the impossibility of reason.

I definitely love history. I'm not formally trained or educated in history, but you could say I did go back to college in 2008 to do Untold History of the United States. That took five years. Co-author Peter Kuznick has been teaching history for something like 35 years, at American University and other places. His group of researchers brought me into contact with a lot of books.

[Nixon] reduced the meaning of his life to nothing but power. In the film, we gave this sad figure consciousness of what he was. We weren't right to do that - I don't think he did have that consciousness. But we did it for movie reasons - to create empathy.

I want my children to have access to something that looks beyond what I call the tyranny of now. You read the paper, everyone talks about that thing [in the news] that day, and all the subconscious really important stuff that's going on is being neglected. The beauty of history is that historians have the ability to find patterns, the big picture. When you make a movie, you try to find that. I'm doing in the cinema what historians try to do in their own media.

A life like Nixon's is filled with shame and filled with glory. He loved to quote Teddy Roosevelt: "He was a man; sometimes right, sometimes wrong, but he was a man." I love that line.
