Invisible Invaders

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.

Directed by Edward L. Cahn, Invisible Invaders leans on a strong ensemble — John Agar, Jean Byron, Philip Tonge — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about science fiction titles of 1959.
