A lot of the good cameraman who we used are doing television work; they're doing commercials for a lot of money. And the commercials look incredible. But what's it about? I made three major commercial campaigns. I enjoyed it, I experimented with it, and at the end of the day I felt no satisfaction. It was like having a fast food lunch.

When I go to the movies, and I have to sit through ten previews of films that look [alike] and tell the whole story, you know that we've reached an age of consensus. And consensus is the worst thing for us. We all agree to agree. That's where we lose it as a culture. We have to move away from that.

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.

Pat Nixon was called the Mona Lisa of American politics. She never wrote anything. Her interviews tell us nothing.

All the Greek mythic heroes had gone east, but they were myths. Achilles was a myth. Perseus, Theseus, Hercules... they probably existed in some form. But they all went east. That's where a Greek went to make his bones so to speak. And Alexander the Great was the first man who actually went east not to plunder, not to loot and come back to Greece - which is where the Macedonians wanted to go back with the money. He stayed. And he became half-Eastern.

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.

Every time you go into a movie, you go into the point of view of who it is about.
