Like many movies in the decades to come, the classic zombie film White Zombie spawned a terrible sequel, Revolt of the Zombies. It's a sequel in the sense that it had the same director and used some footage from the first movie, but the resemblance ends there. The acting ranges from hammy to flat, and the writing is full of cliches. The budget was miniscule, as evidenced by one scene where the characters are shown to be in Cambodia by walking in front of a screen showing stock footage of a Cambodian building.
The story centers around a military expedition attemping to destroy the secret of making zombies to prevent their use in war. A timid archeologist discovers the secret just after being jilted by his fiancee for his friend, and he uses his newfound power to set up a fortress and win back the woman he loves. There is not much more to the plot than that. They attempt to recapture some of the mystique that Lugosi brought to the story in the first film, but the best they can do is an actor with fake scary eyebrows who wants the secret for himself. The zombies in this film are really nothing more than hypnotized people; they don't even appear to die, they just fall under the spell and become slaves.
This movie is only interesting as a part of the history of the genre, but other than that it doesn't have much to offer.
