Gilligan's Island: Voodoo (1966)

Synopsis
The power of Voodoo once more rears its ugly head on the island, as a sinister Witch Doctor (played by veteran Native American actor Eddie Little Sky) begins stealing items from the Castaways' huts. He then uses this items to fashion voodoo dolls in the shapes of the seven Castaways, for the purpose of turning them all into mindless zombies. But Gilligan (Bob Denver) saves the day with a neat bit of table-turning. ~ Hal Erickson, All Movie Guide
