That's been my thought for quite some time, that the moon landings really happened but if they were using technologies that were far beyond what was publicly known they would want to keep it hidden, or maybe more simple if most of the film was damaged by radiation then the only option would be to fake some film for TV.

Alternatively, and because there's effectively zero evidence, there are those who talk about the secret space program, their tune is generally that they DID make it to the moon, but the aliens living there told them not to come back.
