10 Greatest Murder-Mystery Films That Fooled Us All

1. Psycho

Psycho. The ultimate Hitchcock film. What has become a trope in numerous television shows and movies started off as a bone-chilling murder mystery at the Bates Motel. Janet Leigh plays Marion, an embezzler, who ends up at the secluded Bates Motel and encounters Norman, the utterly creepy motel manager.

This is, excuse the pun, the mother of all murder mysteries. The audience watches as an unknown womanly figure stabs Leigh in her shower - a scene that has now become iconic - to which Norman arrives and removes the body. Our suspicions rise as we are shown the disturbing relationship between Norman and his mother, through flashes of lightning and distorted insults to her son.

But Hitchcock being, well, Hitchcock, forces us to scramble as it is revealed that Norman's mother died years ago, along with her lover. The ending - now used too many times in movies to count - is iconic for shocking the world into silence as we hear the words: "It's sad when a mother has to speak the words that condemn her own son."
