Appears in: The 7th Voyage of Sinbad (1958)
Scariest moment: Fleeing desperately, Sinbad and his crew hurl spears at a very angry Cyclops as the one-eyed monster chases them down a beach.
Weakness: Any damage done to its one eye.

Legendary animator Ray Harryhausen's monsters will never get old. Unlike the creatures visualized in cheaper 1950s schlock like Creature with the Atom Brain and The Brain from Planet Arous, his stop-motion creations possess a special quality that's equal parts simplistic and lifelike. In The 7th Voyage of Sinbad, Harryhausen's Cyclops gives memorable life to one of Greek mythology's greatest beasts. For all their CGI, those recent Clash of the Titans movies have nothing on it.
