When filmmakers Ken Burns and Lynn Novick began research for a 10-part PBS documentary on the Vietnam War, they thought they knew the material. After all, Burns was of draft age in 1970, though his draft number was too high for him to be called to serve.
But as they began interviewing subjects and sorting through archival footage, Burns and Novick soon came to appreciate just how complicated the war was. "We went in, both of us, with this kind of arrogance about it, and immediately had that blown out of the water," Burns says. "We realized we knew nothing."
