The Crawling Eye (1958)

The Trollenberg Terror (a.k.a. The Crawling Eye in the United States) is a 1958 independently made British black-and-white science fiction monster film drama, produced by Robert S. Baker and Monty Berman, directed by Quentin Lawrence, that stars Forrest Tucker, Laurence Payne, Jennifer Jayne, and Janet Munro. The special effects were handled by Les Bowie.[2] The story was based on a 1956 British ITV "Saturday Serial" television programme[3] written by George F. Kerr, Jack Cross and Giles Cooper, under the collective pseudonym of "Peter Key." The film was distributed in the U.K. by Eros Films Ltd. in October, 1958[4] as The Trollenberg Terror, and in the U.S. by Distributors Corporation of America as The Crawling Eye. It was released in the U.S. on July 7, 1958[5] as a double feature with the British science fiction film The Strange World of Planet X (a.k.a. Cosmic Monsters in the United States).

The Trollenberg Terror's storyline concerns United Nations troubleshooter Alan Brooks, later joined by journalist Philip Truscott, investigating unusual accidents occurring in the area of a resort hotel on (the fictional) Mount Trollenberg in Switzerland. Brooks suspects these deaths are related to a series of similar incidents that occurred three years earlier in the Andes Mountains, which involved an unexplained radioactive mist and an odd cloud formation believed by locals to be inhabited.
