The Shining is a 1980 psychological horror film produced and directed by Stanley Kubrick and co-written with novelist Diane Johnson. It is based on Stephen King's 1977 novel of the same name and stars Jack Nicholson, Danny Lloyd, Shelley Duvall, and Scatman Crothers. Nicholson plays Jack Torrance, a writer and recovering alcoholic who accepts a new position as the off-season caretaker of the Overlook Hotel. Lloyd plays his young son Danny, who has psychic abilities, which he learns about from head chef Dick Hallorann (Crothers). Danny's imaginary friend Tony warns him the hotel is haunted before a winter storm leaves the family snowbound in the Colorado Rockies. Jack's sanity deteriorates under the influence of the hotel and the residents, and Danny and his mother Wendy (Duvall) face mortal danger.

Psychological horror is a subgenre of horror and psychological fiction with a particular focus on mental, emotional, and psychological states to frighten, disturb, or unsettle its audience. The subgenre frequently overlaps with the related subgenre of psychological thriller, and often uses mystery elements and characters with unstable, unreliable, or disturbed psychological states to enhance the suspense, horror, drama, tension, and paranoia of the setting and plot and to provide an overall creepy, unpleasant, unsettling, or distressing atmosphere.
