king of the zombies

King of the Zombies (1941) horror comedy film produced by Monogram Pictures.

During World War II, a small plane somewhere over the Caribbean runs low on fuel and is blown off course by a storm. Guided by a faint radio signal, they crash-land on an island. The passenger, his manservant and the pilot take refuge in a mansion owned by a doctor. The quick-witted yet easily-frightened manservant (Mantan Moreland) soon becomes convinced the mansion is haunted by zombies, and confirms this with some of the doctor's hired help. Exploring, the three stumble upon a voodoo ritual being conducted in the cellar, where the doctor, who is in reality a foreign spy, is trying to acquire war intelligence from a captured US Admiral whose plane had crashed in a similar fashion on the island. But the interruption causes the zombies to turn on their master.
