10 Movie Plot Twist Clues We All Ignored

Near the end of Alfred Hitchcock's Psycho, Norman Bates (Anthony Perkins) has an argument with his mother before picking her up and taking her down from her room to the fruit cellar.

While he's moving her down the stairs, she shouts at Norman to put her down, yet it's hilariously obvious that Anthony Perkins isn't actually carrying a real person - it's very clearly a mannequin instead.

On a first viewing this seems like a gaffe on Hitchcock's part, that he framed the shot in such a way as to accidentally reveal the artifice of it, but in actual fact that's not really true at all.

At the very end of the film it's of course revealed that "Mother" has been dead for an entire decade, yet Norman has been treating her mummified corpse as though she were still very much alive ever since.

As such, it makes absolute sense that Mother seems a bit, well, brittle and stiff when he's carrying her, because she totally is.
