Errol Morris is like no other documentarian. His subject matter has ranged from people unjustly convicted of crimes to Holocaust deniers who design electric chairs. His films neither condemn nor applaud his subjects. That's why he's the perfect choice to investigate the controversial life of Vietnam War-era Secretary of Defense Robert S. McNamara. McNamara is now in his eighties and is still as sharp as he was when he was considered a government whiz kid.
The wrinkled old man in this documentary doesn't look like someone who helped orchestrate the firebombing of Japanese civilians during WWII, played a key role in the Cuban Missile Crisis or called many of the shots during the Vietnam War, but he is. Morris doesn't interrogate; he simply lets his subject speak, and his defense/explanation of the choices he made is compelling--if disturbing--viewing. Clearly, Fog is mesmerizing stuff.
