L'occhio nel triangolo

The tourists Rose (Brooke Adams), Chuck (Fred Buch), Norman (Jack Davidson) and Beverly (D.J. Sidney) hire the boat of Captain Ben Morris (John Carradine) and his crew, the pilot Keith (Luke Halpin) and the cook Dobbs (Don Stout). While navigating during the night, Keith crashes on a ship and on the next morning they realize that the vessel is stranded and Ben is missing. They go to a nearby island on a small boat and they find Ben drowned. They find a derelict hotel and soon they find they are not alone. A weird man asks them to go away since they are in danger. Later he explains that he was a SS Commander (Peter Cushing) responsible for his powerful troop of zombie Nazis. Now they are returning and soon the group will die.

"Shock Waves" is a funny movie with aquatic zombies. The cast is great with John Carradine, Peter Cushing and Brooke Adams in the beginning of her career. However the story does not give much explanation why the zombies return to the island and how the group of tourist is fed while in the island. My vote is six.

Title (Brazil): "Ondas do Horror" ("Waves of Dread")
