The Wolf Man (1941)
A practical man returns to his homeland, is attacked by a creature of folklore, and becomes infected with a horrific disease his disciplined mind tells him cannot possibly exist.
After teasing his friends for believing in werewolves, Larry (Lon Chaney Jr.) is promptly bitten by a rabid wolf and faints. Horror superstars share the screen when Larry wakes to find a fortune-teller named Maleva (Maria Ouspenskaya) who reveals to Larry that the animal which bit him was actually her son Bela (Bela Lugosi) in the form of a wolf. Cursed by the werewolf's bite, Larry suffers torturous full-moon transformations and tries to escape the townsfolk who hunt him. Claude Rains, Evelyn Ankers, and Ralph Bellamy also grace this classic B movie.
