The trailer for The Wolf Man (1941).
Larry Talbot (Lon Chaney, Jr.) returns to his ancestral home in Llanwelly, Wales to reconcile with his father, Sir John Talbot (Claude Rains). While there, Larry becomes romantically interested in a local girl named Gwen Conliffe (Evelyn Ankers), who runs an antique shop. As a pretext, he buys something from her, a silver-headed walking stick decorated with a wolf. Gwen tells him that it represents a werewolf (which she defines as a man who changes into a wolf "at certain times of the year.")
That night, Larry attempts to rescue Gwen's friend Jenny from what he believes to be a sudden attack by a wolf. He kills the beast with his new walking stick, but is bitten in the process. He soon discovers that it was not just a wolf; it was a werewolf, and now Talbot has become one. A gypsy fortuneteller named Maleva (Maria Ouspenskaya) reveals to Larry that the animal which bit him was actually her son Bela (Béla Lugosi) in the form of a wolf. Bela had been a werewolf for years and now the curse of lycanthropy has been passed to Larry.
Sure enough, Talbot prowls the countryside in the form of a two-legged wolf. Struggling to overcome the curse, he is finally bludgeoned to death by his father; with his silver walking stick. His father watches in horror as his son transforms back into a human and as the police rush into the scene.
