I honestly don't get it! How is it possible that this movie was so dreadfully boring in spite of all the indicators of pure 70's entertainment? Look at all the potentially great stuff here: we have a plot about cursed treasures in sunken galleons, the robust macho actor Stephen Boyd, marvelously exotic Granada filming locations, Jordan Ladd's equally astounding mother Cheryl in a tiny bikini, shark attacks and boat explosions! Adventure movies like this are practically a guaranteed success, yet somehow director Virginia L. Stone managed to ruin the formula entirely. How? Through a combination of inexplicably slow pacing, completely inappropriate slapstick elements and a ridiculous Benny Hill-esquire score and the overuse of irritating clichés (like villains with atrocious German accents). At the scene of a crime, homicide inspector Hugo Graham finds an ancient treasure map that supposedly carries a curse with it. All the previous nine owners of the map died violent deaths, regardless of whether they even attempted to track down the treasure or not. Fascinated by the mystery, Graham takes a photocopy of the map and mobilizes four of his friends to go treasure hunting during his annual vacation. As if the film itself isn't boring enough yet, there's also Boyd's completely unnecessary and monotonous narration. The action sequences and stunts are poorly handled, stupid and too obviously fake. All the available budget for this movie clearly went to the waterproof camera equipment and location hunters. Admittedly the underwater photography is impressive and the Jamaica/Granada locations look like postcards, with their crystal blue waters, colorful reefs and tropical sandy beaches.
