Continuity mistake: When the Highway Patrol Officer hands the driver license back to Marion, in the interior shot he's holding it out with his right hand and Marion takes it with her left hand, but in the next exterior shot he's handing it to her with his left hand and Marion is taking it with her right hand.

Trivia: Alfred Hitchcock adapted Psycho from a story by author Robert Bloch, who had modeled the character of Norman Bates after Ed Gein, who is suspected to have killed his victims between 1954 and 1957. In the asphyxiation death of his brother Henry (who was verbally critical of their neurotic-controlling mother) in 1944, though the supposedly harmless young Gein was quickly dismissed as a suspect, it's believed that he was guilty of that crime too. Other characters very loosely based on Gein are Buffalo Bill in "The Silence of the Lambs" (1991) and Thomas Hewitt in "The Texas Chainsaw Massacre" (1974). The main similarities to Gein that appear in "Psycho" include the feminine qualities of Norman Bates and the disturbingly strong attachment to the cruel domineering mother.
