Invisible aliens stationed on the moon have had enough of Earth's atomic tomfoolery. So they use reanimated dead bodies of humans to let the nations of the world know they mean business, delivering an ultimatum that Earth better surrender to them or else! Now a group of people gather together in a bunker laboratory to work on a way to defeat the invisible invaders while zombies lurk outside.

Edward L. Cahn directed this campy and cheap sci-fi movie with a muddled anti-nuke message. The special effects are poor with an overuse of stock footage and a monotone narration (one of the staples of no-budget sci-fi flicks back in the day). Still, Cahn produces a reasonable amount of atmosphere and it kept my interest throughout. The short runtime helps. It stars washed-up stars John Agar, John Carradine, and Robert Hutton, along with Jean Byron (of Patty Duke Show fame) and venerable character actor Philip Tonge. Other reviewers have pointed out that the movie might have inspired Night of the Living Dead. Whether that's truly the case or not, I don't know, but it is certainly something for movie buffs to chew on. Not a particularly good picture but fun in its way. Fans of '50 sci-fi will like it more than most.

Spooky little horror film that had tentacles which reached far and wide. Many other filmmakers may have taken a dip in this cinematic pool. Don't snicker. Checkout the walking stiffs in business suits staggering around the countryside. Remind you of anyone? The last survivors--holed up in some sought of army bunker--predict a future bird flick. The clash between scientists, civilians and the military is always a staple of the action genre. There may be others, but I would have to watch it again. I first saw this on Creature Feature back in the 70's. It spooked me out to the degree that I swore off this type of movie until Chiller Theatre came on later that night. I came across it again about a dozen years ago when it turned up on New Year's Eve. Weird. Someone's idea of a joke? Recently, I bought it in tandem with another John Agar film called Journey to the Seventh Planet. John Carradine stumbles around as one of the corpses and does very well. Some of the extensive stock footage defies logic. A plane crashes into a marked bulls-eye on a hillside. It looked like a military training ground. The invaders are defeated with the simplest of weapons. They usually are.
