Designed as a follow-up to the Halperin Brothers' phenomenally successful White Zombie, Revolt of the Zombies unfortunately isn't nearly as good. The story is set in Cambodia in the years following WWI. Evil Count Mazovia (Roy D'Arcy) has come into possession of the secret methods by which dead men can be transformed into walking zombies and uses these unholy powers to create a race of slave laborers. An expedition is sent to the ruins of Angkor Wat, in hopes of ending Mazovia's activities once and for all. Unfortunately, Armand (Dean Jagger), one of the members of the expedition, has his own agenda. Stealing a set of secret tablets, he sets about to create his own army of zombies, targeting those whom he considers to be enemies. But Armand is hoist on his own petard when the zombies rebel and turn against him. The anachronistic moviemaking techniques which contributed so much to the atmosphere and entertainment value of White Zombie are totally out of place in Revolt of the Zombies; also, Dean Jagger's performance lacks the conviction necessary for this sort of horror fare.
