was this a fake documentary?
I mean, i get that the subject matter is a real topic, but from the very first interview subjects, i never once got the impression i was watching real people. It all appeared staged, like a 1950's propaganda film, where they re-enact scenarios.
It was really subtle, but i think they didn't realize back then how a human can distinguish between reality and fiction with little cues.
The actors never acknowledged the camera...
Then they'd do an over-the-head shot, then the take from the opposite angle, but then 'other' camera isn't present in either shot...
Then, the camera would just happen to be filming and zooming in at a crucial juncture, like when 2 people kiss, or some guy hands off a piece of paper... all very choreographed.
I'm not saying it was 100% all staged, but i definitely think a great chunk of it was.
