Aliens, contacting scientist Adam Penner, inform him that they have been on the moon for twenty thousand years, undetected due to their invisibility, and have now decided to annihilate humanity unless all the nations of earth surrender immediately. Sequestered in an impregnable laboratory trying to find the aliens' weakness, Penner, his daughter, a no-nonsense army major and a squeamish scientist are attacked from outside by the aliens, who have occupied the bodies of the recently deceased.

Did You Know?


Due to the film's meager budget, cast members had to perform their own stunts with little preparation or training. According to Robert Hutton, this almost led to disaster at least once during the shoot. John Agar very nearly overturned a jeep carrying himself and Hutton during a scene in which he was instructed to brake and swerve sharply. The jeep tilted onto two wheels and very nearly toppled over with the actors inside. See more »


Though the invaders' spaceship in the scenes toward the film's end is supposed to be invisible, it's actually visible throughout the sequence until just before it's destroyed, when it briefly does become invisible. See more »


Phyllis Penner: You killed a man in cold blood this morning, I keep seeing his face.
Maj. Bruce Jay: So do I, I fought all the way through Korea, probably killed a lot of men... but I never saw their faces. Dropping a bomb from a plane isn't quite so personal.
Phyllis Penner: Can I make you some coffee?

"We cannot be defeated. We have never been defeated!"
24 July 2015 | by (USA) – See all my reviews

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.
