Only just caught on to this...
Sorry to resurrect this one, but have a pet theory that one or two others have touched on.
Basically, the US did get to the Moon, but not until Apollo 14.
Faked 11, cos if they hadn't the USSR would have got there first. Cost 'em loadsamoney, but political kudos was at stake: did send rocket up, but didn't go all the way. Needed Hollywood's expertise, hence "Diamonds are Forever" reference: besides, as has been pointed out, if you show the Apollo 11 film at 2x speed, it looks like two blokes in space suits running about a desert at night under spotlights; puffs of dust behave like, well, terrestrial puffs of dust, etc.
12 was sent as far as Moon, wasn't meant to land, just for close range shufti and to test if rad shields worked that far out: didn't want to go to expense of faking pictures again, so did it all in sound, which is a damn sight cheaper, and claimed equipment frizzed out.
13 was, ironically, meant to land, but we all know what happened to that.
So 14 did land, in glorious technicolor.
First man on the Moon? Pete Conrad.
Or possibly Andy Kaufman...
