Gee, who should I believe?

Hundreds of professionals, scientists and laypeople who actually worked on a project that said it DID happen, or a bunch of conspiracy nuts that have no knowledge of basic science?

Looking at the first site you posted, on two of the pictures I could figure out why the pictures were the way they were, and I'm far from a scientist.

Anyone ever interview someone who supposedly worked on these films?

No.

Just like the 'bomb' in the WTC, you will never find anyone who actually did the work, just lots of speculating by people who have nothing better to do.

Oh, and one more thing....

But didn't NASA have good reasons for faking the Apollo missions? What about the Russians?
Absolutely. America was desperate to land on the moon before the USSR, and J.F. Kennedy had made it's NASA's responsibility to do so within a decade. The embarrassment if they had failed would have been considerable. You have to remember that the main driving force behind the Apollo missions was political, not scientific or military. It was a question of putting the commies in their place.

But, having said all that, none of this is proof that they did fake them. And you can be sure that if they were faked, the USSR would have made sure everyone knew about it. They would have been able to tell better than anyone if the missions were faked.
