Today The Shining is hailed as one of the greatest horror movies ever made. But did you know Stephen King, the man who wrote the novel The Shining is based on, is not a fan of the film? He told Playboy he was “deeply disappointed in the end result” in 1983. That’s just one of The Shining facts featured in the newest episode of You Think You Know Movies!

King wasn’t a fan of Jack Nicholson’s casting in The Shining, either. Having already starred in One Flew Over the Cuckoo’s Nest, and boasting one of the most famous crazy grins in the history of movies, King felt that audiences would assume Nicholson’s character, Jack Torrance, was crazy right from the very beginning, dulling the impact of his slow descent into madness. Audiences saw it differently, and today The Shining is considered one of Nicholson’s greatest performances. (Maybe King was just angry that Stanley Kubrick completely rewrote his screenplay, or that the film’s most famous line, “Heeeeere’s Johnny!”, was a Nicholson ad lib.)
