well what I have been reading lately is that of stanley kubrick was asked to help in the filming of the moon landing which is a fake ! by the then president Richard Nixon, Kubrick was filming 2001 A Space Odyssey at that time in MGM studios in london, Kubrick agreed to lend the film set for a weekend to a group of eight CIA Agents sent secretly by the White House who then filmed the Moon walk which was later broadcasted around the world.

Fearfull of the secret filming getting out Nixon ordered the CIA agent to be terminated, Eight of the Agents involved in the london Filming some fled to south East asia & a French Monastry all were dead within a couple of months, Kubrick in return got use of a special NASA Camera for the filming of Barry Lyndon but became a recluse in his own home fearfull of his involvement and knowledge of Nixons secret filming afterwards most of Kubricks film were filmed & Produced from his home and around his estate.
