"What Mrs. Kubrick discovered was that - instead of making a science fiction film called 2001: A Space Odyssey - her husband was really working to create the fake Apollo moon landings.
At this point the film finally gets really interesting. Frightened by this revelation Wendy (Stanley’s wife) wants Jack (Stanley) to quit the Project.
Jack (Stanley) angrily replies: “That is so typical of you! â?¦ I’ve made an agreement â?¦ I have obligations to my employers!”
Danny uses The Shining to contact Dick Halorann in Florida (which I might add is where Apollo 11 was launched). Dick laboriously travels from Florida to Colorado.
In another abrupt break with the novel, Jack Torrance kills Halorann as soon as he arrives at the Overlook (so much for Halorann’s psychic abilities!)
While I think this scene is very disturbing and I doubt if I can ever prove this but I think Stanley Kubrick is telling us something very definite with this alteration to the King novel.
I believe that the naÃ¯ve side of him, represented by Danny, told someone that he, Kubrick, was faking the Apollo missions. He may even have told this person that he was faking the lunar landings for NASA while also appearing to produce the film 2001: A Space Odyssey. Halloran is the representation of the person that Kubrick mistakenly revealed this most secret of all information. Because of that, Halloran, or the person who Stanley told, had to die."
