Female of the Species on AllMovie

Hoping to win back her now-married lover Carleton Condon (Howard Hickman), vampish Gloria Marley (Dorothy Dalton) gets her chance when she accidentally meets Condon on a train. Shortly thereafter, the train is wrecked, resulting in several casualties. Throwing her coat over the body of one of the victims, Marley convinces Condon, who's been rendered an amnesiac by a blow on the head, that the dead man is him, and that he, Condon, is a different person entirely. Marley and Condon move to another town and are married under an assumed name. And then, Condon's "widow" Marcia Dorn (Enid Markey) shows up....Years later, during the television era, Female of the Species co-star Enid Markey specialized in such dithering "old biddy" roles as Don Knotts' landlady on The Andy Griffith Show.
