I believe its real.

As we all know there was a space race going on and the fact that America reached the moon first and was also being televised across the world do you really believe that the Russian's or anyone else for that matter would not want to prove that it was fake?

How difficult would it be for someone to pull out their telescope and have a look at the moon at the co-ordinate that where known of the landing take a few photos and prove the whole thing fake?

I'm sure Russia, Britain, Canada, Japan etc etc would have telescopes powerful enough to see the landing sight and the landing shuttle.
