or adopt an alternative personality. These were the functions and characteristics of Norman Bates, and Norman Bates didn't exist until I made him up. Out of my own imagination, I add, which is probably the reason so few offer to take showers with me." Though Bloch had little involvement with the film version of his novel, which was directed by Alfred Hitchcock from an adapted screenplay by Joseph Stefano, he was to become most famous as its author. Bloch was awarded a special Mystery Writers of America scroll for the novel in 1961. The novel is one of the first examples at full length of Bloch's use of modern urban horror relying on the horrors of interior psychology rather than the supernatural. "By the mid-1940s, I had pretty well mined the vein of ordinary supernatural themes until it had become varicose," Bloch explained to Douglas E. Winter in an interview. "I realized, as a result of what went on during World War II and of reading the more widely disseminated work in psychology, that the real horror is not in the shadows, but in that twisted little world inside our own skulls." While Bloch was not the first horror writer to utilise a psychological approach (it originates in the work of Edgar Allan Poe), Bloch's psychological approach in modern times was comparatively unique. Bloch's agent, Harry Altshuler, received a "blind bid" for the novel – the buyer's name was not mentioned – of $7,500 for screen rights to the book. The bid eventually went to $9,500, which Bloch accepted. Bloch had never sold a book to Hollywood before. His contract with Simon & Schuster included no bonus for a film sale. The publisher took 15 percent according to contract, while the agent took his 10%; Bloch wound up with about $6,750 before taxes. Despite the enormous profits generated by Hitchcock's film, Bloch received no further direct compensation. Only Hitchcock's film was based on Bloch's novel. The later films in the Psycho series bear no relation to either of Bloch's sequel novels. Indeed, Bloch's proposed script for the film Psycho II was rejected by the studio (as were many other submissions), and it was this that he subsequently adapted for his own sequel novel. The film Hitchcock (2012) tells the story of Alfred Hitchcock's making of the film version of Psycho. Although it mentions Bloch and his novel, Bloch himself is
