Gli adoratori della morte

This is one of Boris Karloff's last films. It's a confusing train wreck featuring Karloff as Damballah / Carl van Molder, a sexy-as-hell snake dancer named Tongalele, a maniacal grinning dwarf, zombies, and lots of big snakes of course. The basic premise of the movie is that the island has been taken over by zombies and followers of a voodoo cult who worship their leader, Damballah. The local police force are more interested in finding the bottom end of a rum bottle than they are in stopping the activities of the voodoo cult. A superior officer of the police arrives on the island to clean things up, and he tries to enlist the help of a large plantation owner, Carl van Molder. Van Molder is uninterested in helping the police, telling them to leave things as they are, that they don't know what they're messing with.

It's campy but fun, I've seen a lot worse that's for sure.
