The differences between the book
version of The Shining are numerous.
The biggest difference would be the end to the story. In the book, Wendy and Danny manage to escape the hotel with the help of Mr. Halloran before it explodes. This explosion is the result of Jack forgetting to check the boiler gauge in the basement. The movie, however, ends with Mr. Halloran being killed with an axe by Jack, and Jack later freezing to death in the hotel gardens.
Other notable differences include missing scenes, that were obviously omitted when creating the movie. The scene with the enchanted shrubbery animals isn't present, as well as Danny's beehive that, one night, suddenly bears angry insects.
