For the scene in which Jack breaks down the bathroom door, the props department built a door that could be easily broken. However, Jack Nicholson had worked as a volunteer fire marshal and tore it apart far too easily. The props department were then forced to build a stronger door.
Jack Nicholson and Shelley Duvall have expressed open resentment against the reception of this film, feeling that critics and audiences credited Stanley Kubrick solely for the film's success without considering the efforts of the actors, crew, or the strength of Stephen King's underlying material. Nicholson and Duvall have said that the film was one of the hardest of their careers. In fact, Nicholson considers Duvall's performance the most difficult role he's ever seen an actress take on. Duvall also considers her performance the hardest of her life.
Stanley Kubrick, known for his compulsiveness and numerous retakes, got the difficult shot of blood pouring from the elevators in only three takes. This would be unremarkable if it weren't for the fact that the shot took nine days to set up. Every time the doors opened and the blood poured out, Kubrick would say, "It doesn't look like blood." In the end, the shot took approximately a year to get right.
Jack Nicholson suggested Scatman Crothers for the film. Crothers had a tough time on this movie, with Stanley Kubrick making him do over one hundred takes for one scene. Crothers' next film was "Bronco Billy (1980)," directed by Clint Eastwood, who was famous for generally only going with one take. Crothers broke down in tears of gratitude on his first scene in the film when he realized he wouldn't have to do so many endless takes.
The throwing around of the tennis ball inside the Overlook Hotel was Jack Nicholson's idea. The script originally only specified that "Jack is not working."
