Cassandra Peterson (born September 17, 1951) is an American actress best known for her portrayal of the horror hostess character Elvira, Mistress of the Dark. She gained fame on Los Angeles television station KHJ wearing a revealing, black, gothic, cleavage-enhancing gown as host of Elvira’s Movie Macabre, a weekly horror movie presentation. Her wickedly vampish appearance is offset by her comical character, quirky and quick-witted personality, and Valley girl-type speech.
