Isle Of The Snake People (1971)

Isle of the Snake People is a surreal, low-budget Mexican-American horror film directed by Juan Ibáñez and Jack Hill, starring the legendary Boris Karloff in one of his final roles. Though filmed in 1968, it wasn’t released until 1971, two years after Karloff’s death, and is part of a quartet of films he made in a package deal with Mexican producer Luis Enrique Vergara.

Plot Summary
Set on the remote Pacific island of Korbai, the story follows Captain Pierre Labesch, a mainland officer sent to crack down on lawlessness and bizarre voodoo rituals. He encounters Annabella Vandenberg, a temperance crusader seeking help from her uncle, Carl van Molder (Karloff), a plantation owner with mysterious ties to the island’s occult practices.

As Annabella is drawn into the island’s dark underbelly, she’s kidnapped by a cult led by the sinister priest Damballah, who plans to sacrifice her to resurrect Baron Samedi, leader of the undead. Meanwhile, native women are transformed into zombies by a snake-dancing seductress named Kalea, and the island descends into supernatural chaos.

Legacy
