The Crawling Eye (1958)

Synopsis
The Trollenberg Terror was adapted for the screen by Jimmy Sangster from the popular BBC TV serial by Peter Key. At the remote Alpine village of Trollenberg, someone or something is killing off mountain climbers. The culprits turn out to be an army of one-eyed, tentacled, beasts from outer space, who hide themselves in a radioactive cloud. Crawling along like snails, these horrific creatures attempt to neutralize their human foes by pumping a freezing fog at their pursuers. It helps matters not at all that some of the locals have been mentally enslaved by the monsters. It's up to American scientist Alan Brooks to save the day. The Trollenberg Terror was retitled The Crawling Eye when it was released in the U.S. on a double bill with The Cosmic Terror. ~ Hal Erickson, All Movie Guide
