I recently borrowed a copy of Jay Weidner's "Kubrick's Odyssey Secrets Hidden in the films of Stanley Kubrick." Part One concerns the Apollo moon landings. Weidner makes an excellent case showing the same technology used in "2001: A Space Odyssey" is the same technology used in the faking of the landings. Further, Kubrick appears to have confessed via clues put in "The Shining."
It's really worth the watch. Note that Weidner takes a somewhat safe approach stating he believes the filming was faked so the Russians wouldn't be able to see America's technology. Obviously I think he's wrong and that reasoning doesn't fly 45 years later but I'll give him a pass considering his discovery.
