just before he die boris karloff shot back to back footage for four poverty row horror flick . additional scene be later shoot in mexico with mostly different actor . to bring each of them up to feature length . this be the first and most coherent of this unfortunate quartet of picture . it also the dull . boris be a plantation owner on an island threaten by a curious voodoo cult that throw in cannibalism and snake worship with the usual business plan of raise of the dead to work in the field . the story be bereft of any new idea and the phallic imagery be rather puerile . still and we do get some lively snake dancing and the matching of the two set of footage be not that bad and although karloff foreman appear in one scene with a beard and the next scene without . if only the great man have stop here .
