Robert S. McNamara became famous as the Secretary of Defense who directed much of the Vietnam War. He was a former auto executive and one of the great minds of his generation -- a man who sought to bring order and reason to the chaos of war.
Three decades later, McNamara wrote a book that was seen as a kind of apology for the disasters of Vietnam. But filmmaker Errol Morris was convinced that McNamara still had something more to say. He persuaded McNamara to sit down for a series of interviews that became a documentary: The Fog of War.
