Errol Morris, the mad scientist of American documentary filmmaking, has masterminded a stream of innovative and completely distinctive works. Though his latest, The Fog of War, is conventional in structure, its subject, Robert McNamara, is anything but. McNamara, the Secretary of Defense under Kennedy and Johnson, was the architect of the Vietnam War — he's the man who famously applied mathematical principles to the battlefield. But The Fog of War is no by-the-numbers history piece; McNamara is the sole voice in the film, and he's surprisingly frank, at one point equating his actions to war crimes. The Fog of War is both an indelible portrait of a major historical figure and a revelatory examination of America's use of military force, then and now. (JS)The Fog of War official website
