I don't think that there has been a film that I've done that hasn't been influenced by libraries and archives.

It follows the seasons, beginning each year with the fond expectancy of springtime and ending with the hard facts of autumn.

I think we continually need to understand how important an event the war was - how defining, how central to who we are. Everything that came before it led up to it, and everything of importance to this country - at least up to 1940 - was a consequence of it. Even now there's an echo of the war, however faint, in almost everyone's life.

World War II is smothered in sentimentality and nostalgia. What's interesting about Vietnam is that sentimentality is just not there, so you're given kind of a clean access to it in one way. It's also a war that represents a failure for the United States. Many people came back feeling like they never wanted to talk about it again. And so we developed a national amnesia.

You need, as a historian, essential triangulation from your subject and the only way you get that triangulation is through time.

I think my expectations for myself are much more severe and much more direct. You can't work on a film for six years without being your own toughest critic. So you can't really be distracted by the expectations based on your previous performance.

I have come to the realization that history is not a fixed thing, a collection of precise dates, facts and events (even cogent commencement quotes) that add up to a quantifiable, certain, confidently known, truth. It is a mysterious and malleable thing.
