The Crawling Eye on AllMovie

The Trollenberg Terror, authored by Peter Key and directed by Quentin Lawrence, started life on British television as a six-part installment of ITV's Saturday Serial in late 1956 and early 1957. The big-screen version, was adapted by Jimmy Sangster, who compressed most of the best horrific and mystery elements of the original into an under-90-minute vehicle, which Lawrence directed. At a remote Alpine village, mountaineers suddenly start dying, their bodies horribly multilated -- at first, these incidents seem like they could just be accidents. But the arrival of a pair of sisters (Janet Munro, Jennifer Jayne), one of whom feels an almost telepathic connection with someone or something on the mountain, attracts the interest of American Alan Brooks (Forrest Tucker), a trouble-shooter for the United Nations. He and Prof. Crevett (Warren Mitchell), who has been monitoring the radiation levels in the area from a research station set up by the government, determine that there is a pattern to these deaths that Brooks has seen before, in a prior incident in the Andes Mountains. They determine that the Earth has been invaded, at high altitude, by a race of gigantic, tentacled aliens who live in thin atmosphere and at extremely low temperatures. Camouflaging themselves in a dense radioactive cloud, they've been content up until now to hide their existence while experimenting with the inhabitants of their new world -- they've taken over some human subjects telepathically, and also re-animated dead bodies. And they've killed those -- such as the hapless mountaineers who have stumbled upon their new lair, or those few humans whose stronger-than-usual mental powers have allow them to sense the aliens' presence -- who threaten to discover them. But now Crevett sees that the aliens are adapting and moving down the mountain, the cloud bringing their necessary cold temperatures with them, and threatening to engulf the village as prelude to an attack on it and all that lies beyond. The Trollenberg Terror was retitled The Crawling Eye when it was released in the United States, in an obvious attempt to draw the same audience that had made the previous year's British film adaptation of a tv serial -- The Quatermass Xperiment, renamed The Creeping Unknown -- into a huge hit in the US.
