I didn't see this one recently and it doesn't have much, or any, space/moon/science. But it does have mankind.
Kim Jong-Il's Comedy Club
http://www.bbc.co.uk/programmes/b00qpk0g
Kim Jong-Il's Comedy Club (BBC4) is a weird and wonderful thing. Three Danes ??? one film-maker and two comedians ??? are allowed into North Korea, supposedly to put on a theatre show, but really to make a film about trying to put on a theatre show. Obviously they are assigned a team of minders to make sure they only see what they're supposed to see, as well as a team of theatre directors, to ensure their performance is acceptable to the state. But, by giving them only what Kim Jong- Il wants, they inadvertently provide the Danes with what they want, too.
It's a brave thing to do, to shake total- itarianism by the hand, then pull out at the last minute and cock a snook at it instead. But the result is terrific ??? both a telling portrait of what it's like to live in fear, and also a hilarious scam that Sacha Baron Cohen would be proud of. The highlight is when they manage to take part in one of those extraordinary, massive marches they go in for over there. One of the Danes is in a wheelchair (a rare sight in North Korea: there are no disabled people), and they shuffle along awkwardly between massive battalions of human obedience, three specks of grit in a well-oiled machine.
