Jack's interviewer, Ullman, is highly authoritarian, a kind of snobbish martinet. The film's Ullman is far more humane and concerned about Jack's well-being, as well as smooth and self-assured. Only in the novel does Ullman state that he disapproves of hiring Jack but higher authorities have asked that Jack be hired. Ullman's bossy nature in the novel is one of the first steps in Jack's deterioration, whereas in the film, Ullman serves largely as an expositor. In Stanley Kubrick and the Art of Adaptation, author Greg Jenkins writes "A toadish figure in the book, Ullman has been utterly reinvented for the film; he now radiates charm, grace and gentility." From Kubrick: Inside a Film Artist's Maze: Ullman tells Jack that the hotel's season runs from May 15 to October 30, meaning that the Torrances moved in on Halloween (October 31). On Ullmann's desk next to a small American flag sits a metal cup containing pencils and a pen – and a miniature replica of an ax. "When Ullman, himself all smiles, relates as a footnote the story about the former caretaker who 'seemed perfectly normal' but nevertheless cut up his family with an ax, Jack's obvious interest (as if he's recalling one of his own nightmares) and his insincere congeniality (early signs of a personality malfunction) lead the viewer to believe that the film's definition of his madness will be far more complex." Family dynamics Stephen King provides the reader with a great deal of information about the stress in the Torrance family early in the story, including revelations of Jack's physical abuse of Danny and Wendy's fear of Danny's mysterious spells. Kubrick tones down the early family tension and reveals family disharmony much more gradually than does King. In the film, Danny has a stronger emotional bond with Wendy than with Jack, which fuels Jack's rather paranoid notion that the two are conspiring against him. The exact opposite is true in the book, where Wendy occasionally experiences jealousy at the fact that Danny clearly prefers Jack to her. Plot differences In the novel Jack recovers his sanity and goodwill through the intervention of Danny while this does not occur in the film. Writing in Cinefantastique magazine, Frederick Clarke suggests, "Instead of playing a normal man who becomes insane, Nicholson portrays a crazy man attempting to remain sane." In the novel, Jack's final act is to enable Wendy and Danny
