How has "Trinity and Beyond: the Atomic Bomb Movie" not been mentioend yet?!?!? Its got great music, william friggin shatner as the narrator and a very interesting set of reflections by Edward Teller and other nuclear scientists about the development of Atomic Weapons.
Also BLACK COFFEE is a very intersting documentary about coffee and its effects on politics and history.
I hate the Corporation.. just a ridiculously muddled documentary.
Fog of War is amazing and well worth seeing.
