Atomic Age aliens create army of the walking dead to conquer Earth! Cue the retro sci-fi Cheese-o-tron!
1 August 2006 | by Death_to_Pan_and_ScanSee all my reviews

I have to admit this was fun to watch despite how ridiculously silly it was or maybe because of that. This isn't a zombie movie in the modern sense, but a sci-fi alien offshoot of the mind-controlled zombies out of the voodoo genre. It's a big slice of black & white American cheese all the way which seems to use a lot of disaster stock footage for invasion scenes that involve conventional sabotage, but it manages to be pretty entertaining anyways.

The director also made 50's sci-fi movie "It! The Terror from Beyond Space" (which helped inspire lots of trapped on a spaceship with a creature film, including "Alien") and the swimming zombified sailors guarding buried treasure film "Zombies of Mora Tau" (which I still haven't seen yet as of writing this review).

THE PLOT: A scientist ditches out on his gov't job because he opposes nukes. A fellow scientist killed in an experiment walks up to his house and has a chat with him, but its not his friend. It's an alien who is none too happy with where out technological advancements are headed (reaching nuclear technology and space travel) and the threat they could pose to their outer space alien race and they want us to surrender or die (this was a common sci-fi plot thread back in the day). They are apparently invisible as are their spaceships awaiting us at their hidden base on the moon and the aliens can take over corpses and walk around in them sabotaging our planet. It's a race against time for the scientists to find a method to combat the alien menace before the walking dead breach the military bunker.

It doesn't have a lot of the elements of modern zombie films like gut munching or turning from being bitten (though the aliens will inhabit your body if you are killed), but it's kinda fun and has some good silly quotes. So bad you might think it's good 50's sci-fi fun.
