12 Movies That Cleverly Gave Away Their Twists Early

6. The Stuffed Birds - Psycho

The Twist

Even those who haven't seen Pyscho will be at least vaguely aware of the twist that Norman Bates is actually the Bates Motel killer who dresses up as his already dead mother (who he murdered along with her mother ten years earlier in a fit of jealousy).

The Reveal

Right at the start of the movie, Norman basically spells out the truth of his mother's condition when he first meets Marion Crane. After she checks in, she overhears him and his mother seemingly having an argument over Norman inviting a woman into her house, in which she is abusive towards her son.

Marion then talks to Norman and suggests their relationship might be somewhat toxic, but Norman defends her, revealing her mental illness and explains to her that his mother is “as harmless as one of those stuffed birds.” She's not just as harmless as them, she's also as dead as them.
