Directed by: Alfred Hitchcock
Starring: Janet Leigh, Anthony Perkins, Vera Miles, John Gavin
Continuity mistake: When Arbogast reaches the top of the stairs, Mother Bates stabs him in the chest; but when the camera angle changes, the wound is on his face.
Suggested correction: That's blood splatter, not the wound.
Revealing mistake: When Marion is driving her car through the night, she keeps looking at her speedometer. You can clearly see that the gear shift lever is in "park" as she is driving.
Norman Bates: A boy's best friend is his mother.
Trivia: Psycho was the first American movie to show a toilet, and hear one flushing - both viewed as inappropriate in that era.
Question: This is a weird question, but was December 11th 1960 actually on a Friday?
Answer: No, it was a Sunday. However, December 11th fell on a Friday in 1959, the year before release.
Answer: The film was shot in 1959 and released in 1960, so the reference to this date being on Friday would be correct.
