Filled with ridiculous plot holes, dumb characters, and an even weaker threat, Zombies of Mora Tau is somehow still enjoyable even with its logical idiocies. This low-budget quickie was obviously shot for somewhere between $2 and $3, yet some decent performances and eerie moments help it along to make this a tolerable little forgotten effort.

Staying away from the typical “radiation made me do it” plotline, this one concerns some diamonds guarded by the shipmates who drowned with them decades ago. They walk the area, guarding the stash from anyone who comes near it. There wouldn’t be much of a movie if another crew wasn’t making an attempt for the millions of dollars buried under the water, and that’s what we have here.

Predictable plotting means the body count is as expected from the early moments. Marjorie Eaton plays the voodoo believer (in excellent make-up to make her look far older than she was) who warns everyone in creepy fashion that they won't make it to the treasure without a fight. Allison Hayes (Attack of the 50 Foot Woman) takes a role as a spoiled wife and runs with it, complete with campy after-effects.

Solid pacing gives the zombies constant screen time. Shots of them disappearing into their watery graves are creepy enough to set the intended atmosphere while the rest of the film destroys it.

Absolutely unforgettable shots of underwater divers searching for the jewels and then being attacked are the stuff of Z-movie legend. Strapped to the back of the diving suits of the adventurers are kids' bubble makers to make it look like they’re underwater. Actors are obviously moving slowly to imitate water movement (poorly), and close ups never match the wide shots.

As told and shown, zombies are afraid of fire or bright light. Hence, most of the characters carry torches with them. Since gunfire doesn’t work to kill the zombie, why not just burn them? One of the characters is eventually turned into one of the living dead and obviously so, but there’s little resistance when they’re brought back to the house and allowed to sleep in a bedroom. The zombies' living quarters inside a crypt seems like an easy way to trap them as well.
