One of the four films that Boris Karloff made at the end of his life. He made four low-budget films for a company that produced the films in Mexico, although Karloff's scenes were shot in California by director Jack Hill. Karloff is visibly old and haggard, and frequently sits through most of his dialogue. I'm afraid that his presence cannot save this film from being utterly tedious and ludicrous. Karloff plays a French plantation owner seemingly connected with some snake cult, voodoo worship, and a lot of weird characters. There is a dwarf that wears crazy glasses and is slain for some inexplicable reason. There is also a woman that stares at people while she dances around with a snake. She has a wild white streak in her hair. The island has a new police chief that acts with all the conviction of a puppet. The actors are all Mexican (except for Karloff and one other actor). The blending of the footage shot in Mexico and that shot in Hollywood is done adequately, however, the film makes little sense. Script and editing are poorly conceived and poorly executed. Poor Boris! At least it is nice to see him again.
