Rating: - Tongue-in-cheek 1959 sci-fi cult film
The story: Earth's scientists are fooling around with the atom again and inhabitants of the Earth's Moon are quite unhappy about it. Of course, once atomic energy becomes a household word, the next thing you know, man will be on the Moon -- and the Moon Aliens plan to put the skids to THAT!

To prevent earthlings from exploring space, the "Invisible Invaders" (alien Moon residents) plan to attack, invade, and take over planet Earth, killing all the Earthlings in the process. Since these moon folks and their spacecraft are invisible it's clearly difficult to do battle with them. The invaders DO pre-warn Earth's residents to just give up the planet, but you know how stubborn Earthlings are. The Invisible Invaders can re-animate corpses so we end up with a sort of either "Night of the Living Dead" or "Invasion of the Body Snatchers" -type scenario as the battle for earth ensues.

As the situation deteriorates for the Earthlings a small band of Earth's scientists ultimately retreat to a secret military bunker where they attempt to devise a new weapon which will derail their alien attackers. It soon becomes apparent to these scientists that the only real weapon that the Moonsters (my word) have is invisibility itself. I'll have to stop there to avoid giving rise to a Spoiler!

The 1959 film, "Invisible Invaders" is shot in black-and-white and runs 67 minutes in duration. The aspect is full frame. Produced by Premium Films, the movie was directed by Edward L. Cahn and the big stars are John Carradine (superb!), John Agar, and Robert Hutton. The music was composed by Paul Dunlap (pretty good) and the special effects are by Roger George.

I'm a huge fan of this genre of period films and this one is okay - the actors played their roles quite well but both the story and the special effects are just a little too silly and absurd. Still, if you savor the old Drive-in Movie sci-fi flicks, "Invisible Invaders" might be right up your alley.
