This was released on a widescreen VHS tape by Anchor Bay a few years back, and if you're a fan of silly, slowly-paced, violent 70's films, you may find it to be fun.
This is a fairly standard treasure hunt film in which some decent people decide to photocopy a supposedly cursed map ("If there was a curse, it could hardly go through a copy machine," the narrator confidently explains) and go looking for the sunken cache of gold. Nice underwater footage of rotting old boats, sharks, coral, and various kinds of grody sea scum. It seems that the diving footage was captured first, and the script then written around it; the film subsequently made with actors wearing diving suits that matched those of the divers in the original footage. At least, that's what it looks like to me. If that is the case, it's pulled off fairly well.
Film is notable, or maybe not, for its 70's-style mean-spirited violence, which provides for some fairly graphic and shocking moments, including sharks munching on a girl, and a face burned on a barbecue. This was before sophisticated gore effects were in vogue, and so most of the violence is achieved with simple makeup and bright red opaque 70's blood poured all over the place. The intent to startle is clearly there.
As mentioned in another review, there is a G-rated cut of the film available, in case you'd like to see the treasure-hunt stuff without the gruesome, gory violence. This shorter cut isn't too bad either!
Not high art, but it's not a bad movie, really, just a bit of low-budget exploitation.
