"The Shining" is, among other things, a giant metaphor of human (and in particular, western) civilization. The constant references to the moon landing (and 2001: A Space Odyssey) can imho be understood as an one of the many illustrations of the great and unprecedented things that came out of a civilization that is masterfully portrayed in the movie as a fading grand hotel built on a burial ground that is trapped in a seemingly eternal winter. Seeing it as Kubrick's confession that he staged the moon landing is not only silly, it doesn't even begin to describe the film's poetic depth. However, I watched the documentary where this clip is taken from (Room 237 [0]) and can recommend it with reservations. But I remember that it "jumps the shark" somewhere around the middle of the documentary.

Just to elaborate: I often hear people discredit "The Shining" because it didn't scare them enough, or because they think King's book is better, or because they find Duvall's and Nicholson's performances over-the-top. In my opinion, "Shining" is Kubrick's masterpiece. It is arguably deeper than 2001, has a very high artistic quality (some scenes are staged like a ballet) and at the same time, the movie is constantly entertaining and thrilling (which is a quality 2001 clearly lacks, as I have experienced again and again when I tried to watch it with friends who were unfamiliar with Kubrick's work).

To save anyone else this pointless click: that video is total nonsense and the ramblings of a moon landing conspiracy theoryist.

Wow, this is some next-level crackpot tinfoil conspiracy theorist hogwash.
