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.

Factual error: When Janet Leigh is shown lying dead on the floor of the shower, there is a close-up of her open eye. The pupil is contracted to a pinpoint (obviously due to the bright lighting) where it should have been dilated. After the film was released, Hitchcock heard from several ophthalmologists who pointed this out and suggested he use belladonna eye drops in the eyes of "dead" people in future films, as the chemical prevents the pupils from contracting.

Norman Bates: A boy's best friend is his mother.
Question: I'm doing horror movies in my Media Studies course and we're looking at this film in great depth. There were many themes that came up a lot in the film, mainly mirrors, birds and eyes. I've had loads of interpretations of all of these, but does anyone know what they symbolise?
Chosen answer: Birds are just a favourite choice of spooky animal that Alfred Hitchcock seems to use hence the film "The Birds". Eyes show the window to our soul where our deepest fears originate and who isn't scared of getting knifed in the shower. The mirrors i can't explain but I can suggest that it just looks creepy.
