Revolt of the Zombies (1936)
Revolt of the Zombies is a 1936 horror film directed and produced by the Halperin Brothers which stars Dean Jagger and Dorothy Stone. It is one of the earliest zombie films. Although it was conceived as a loose sequel to Victor Halperin's moderately successful 1932 film White Zombie, when compared with Halperin's previous work, this film is generally regarded as a disappointment. Although he is not credited in the film, Bela Lugosi's eyes appear in Revolt of the Zombies whenever zombifying-powers are used; it is the same image of Lugosi's eyes used in the film White Zombie. Revolt of the Zombies is in the public domain, and can be copied or distributed without regard to copyright law.
