The Trollenberg Terror (U.S. title: The Crawling Eye; also known as Creatures from Another World ) is a 1958 British science fiction horror film produced by Robert S. Baker and Monty Berman and directed by Quentin Lawrence. The film stars Forrest Tucker, Laurence Payne, Janet Munro, and Jennifer Jayne. The special effects are by Les Bowie. The story is based on a 1956 British ITV "Saturday Serial" television programme written by George F. Kerr, Jack Cross and Giles Cooper under the collective pseudonym of "Peter Key". The film was released as The Crawling Eye in the United States on 7 July 1958 by Distributors Corporation of America and as The Trollenberg Terror in the United Kingdom in October 1958 by Eros Films. It played on a double bill with the British science fiction film The Strange World of Planet X, retitled Cosmic Monsters for its American release.

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 that these deaths are related to a series of similar incidents which occurred three years earlier in the Andes Mountains, which involved an unexplained radioactive cloud formation believed by locals to be inhabited.
