Vampires have been a fixture of film since Bela Lugosi brought Bram Stoker's Dracula to life on the big screen in 1931. Over the decades the genre has been far from static, as vampire narratives changed and evolved with the appetites of their viewing public. First depicted as formally dressed villains, vampires would later be portrayed as supernatural beings with some human characteristics, and still later as sympathetic figures. Focusing on 19 representative films and television productions, this critical study tracks the evolutionary changes of the screen vampire. It explores the factors that cause a genre to change and examines the alternating cycles of audience expectation.
