A mysterious radioactive cloud hovers on the side of the Trollenberg mountain but no cloud should be at that altitude. In an observatory atop the mountain scientists monitor the behavior of the cloud. Forrest Tucker, who has seen such a cloud before, arrives to investigate. When townspeople start disappearing the cloud appears suspect.
This movie isn't that bad but the monster creatures are so poorly done, they are truly cheesy and the ending reminds me of when I was a boy and used to light plastic army men on fire in the backyard and watch them melt. Just film that and you have the special effects for this film.
The opening scene certainly grabs your attention. There is some nice photography of the Swiss Alps. The acting is fine. Janet Munro is an eye full as the extremely cute psychic who gets manipulated by the monsters.
Crawling Eyes/Trollenberg Terror is a British horror film of the 50's like Day of the Triffids and the Quatermass films.
