The planet Metaluna will perish under the weapon blows of an alien race, but its inhabitants intend to get abundant help from unsuspecting Earth, especially its scientists. This Island Earth (1955) is, then, a tale of two planets, with all the sinister action emanating from Metaluna. Spoken here is a deceptive promise of peace between peoples, but, no, there is no peace, albeit a single alien (Jeff Morrow‘s Exeter) is decent enough to want to help the Earthlings.
Directed by Joseph Newman, this is standard apocalyptic sci-fi, and it’s not bad. No doubt like the story it’s based on, it is considerably unpredictable and it holds one’s attention from start to finish. I question why the Earth scientists are so naive, though.
