Jonathan Drake (Eduard Franz) and his brother Kenneth (Paul Cavanagh) are the latest in the line of Drake men and as such must suffer the curse placed upon the men of their family for ages. This curse dates back for centuries and involves heads being severed and shrunken.
This is an effective touch in the screenplay by Orville H. Hampton, which is fairly strong and violent stuff for 1959. Capable B movie director Edward L. Cahn, whose credits include the sci-fi thriller "It! The Terror from Beyond Space", is at the helm of this decent programmer. It's nothing special, but not bad, either. As one can see, it's not without its creepy elements, although it's awfully talky for much of its running time. It's clearly not too concerned about functioning as a mystery, as our villain is revealed much sooner than we expect, and it becomes a matter of waiting for our protagonists to get caught up to speed.
It benefits from a pretty strong cast. Franz, usually a supporting actor or bit player in features (such as the classic "The Thing from Another World") is wholly believable in a lead role. Grant Richards co-stars as the intrepid police detective Jeff Rowan, who goes through the biggest character arc in the story, as a hard-headed man who believes in rational and sane explanations who's forced to acknowledge some truly unreal things. Valerie French is Franz's worried daughter, Paul Wexler the most memorable character in the film as the Jivaro Indian henchman who's had his lips sewn shut, and Henry Daniell is lots of fun as the intense archaeologist Dr. Emil Zurich.
A short running time (71 minutes) ensures that the story go on no longer than it needs to, while a thunderous score by Paul Dunlap plays in the background. Those shrunken heads, designed by Charles Gemora, are really quite convincing; in general, the special effects, what little there are, are well done. In the end, this little film does have some potency going for it as well as some entertaining climactic action and revelations. Fans of the B movies of the era should find this a reasonable diversion.
