I saw a documentary last year that claimed the moon landing was actually done on a hollywood set and was put together by Stanley Kubrick. They interviewed a lot of famous and powerful people from the late 60's and it appeared as if all of them were fessing up. It didn't take long to realize they were all talking about Watergate and good editing was making it appear as if they were talking about the Moon Landing. I never figured out if this was someone's attempt at fraud or if it was a satire on conspiracy documentaries, but it was funny as can be.
I saw it last year as well. It was fascinating...
If I remember correctly, people like Rumsfeld must have played along in the making of the documentary. I don't think it was all old edited old photage.
