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.

Hostile extraterrestrials reveal themselves to mankind when one takes over the dead body of the deceased Karol Noymann (John Carradine). They've been living in secret on the moon, having exploited the fact that normally they're invisible to the human eye. Now they've decided to conquer the Earth, and only a select few will be able to save the day: intrepid hero Major Bruce Jay (John Agar), Noymanns' associate Dr. Adam Penner (Philip Tonge), Penners' daughter Phyllis (Jean Byron), and young scientist John Lamont (Robert Hutton).This is must viewing if you're a fan of Carradine, Agar, or both. Carradine isn't seen on camera very much, but his booming voice is used to great effect, to function as a voice for the alien intelligence. Agar is as likable as he's ever been. Hutton is fine as the man who begins to crack under pressure. The best performance would have to be from Tonge, however; he's so remarkably sincere that he helps to completely sell the material.Ably directed by prolific B movie specialist Edward L. Cahn ("It! The Terror From Beyond Space"), "Invisible Invaders" does give away the fact that it's low budget from the start, with most of the action confined to one main set - an underground bunker - and a dialogue heavy script. Making a difference are some of the details, such as the way that the creatures manipulate dead human bodies, and the subsequent hordes of the walking dead that prefigure George A. Romeros' landmark horror film "Night of the Living Dead". Our heroes come up with a novel way of confining one of the enemy, and in the end also devise an amusing solution. Despite a lot of talk, the pacing *is* adequate enough, and this clocks in at a very reasonable 68 minutes long.Written by Samuel Newman, who was also responsible for the bad movie classic "The Giant Claw" - which also featured a character named Karol Noymann.Six out of 10.

What a bright idea! How to save thousands of dollars on your "B" movie adventure: Make your invaders invisible! As implied, this is an extremely low-budget, sci-fi horror melodrama from the Robert E. Kent—Edward L. Cahn pill-box. The screenplay by Sam Newman (obviously penned in his lunch hour at CBS TV), begins with some ineptly padded introductory scenes before switching to an enormous amount of stock footage which turns out to be considerably more interesting than the movie itself. Indeed, when the movie itself resumes and director Cahn takes the reins, entertainment flies out the window. Mr. Cahn's painfully inept direction gleans only a minimum of atmosphere and tension from some quite promising Newman material. Admittedly, Cahn is not helped by his fourth-rate cast. The stars, John Agar, Jean Byron and Robert Hutton are particularly weak. Available on an excellent Metro-Goldwyn-Mayer DVD.

The movie was done on a shoestring budget ,for all that demands a lot of money (the adventures of the aliens on their planet,in Space ,on the Moon) is told by a grating voice over which explains everything to us -and another one for the voice of the invader(s)- and sometimes becomes preachy,urging the countries of the world to get together and to stop building their atomic bombs ,which makes the flick look like a rehashed "the day the Earth stood still" as far as moral is concerned).Besides the main idea of the screenplay was borrowed from the highly superior "invasion of the body snatchers" which I urge sci-fi buffs to see immediately if they think that the genre produced only lousy movies in the fifties.The last scene sells the fin de decade audience universal utopia.
