The Trollenberg Terror 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 American audiences.

Forrest Meredith Tucker was an American actor in both movies and television who appeared in nearly a hundred films. Tucker worked as a vaudeville straight man at the age of fifteen. A mentor provided funds and contacts for a trip to California, where party hostess Cobina Wright persuaded guest Wesley Ruggles to give Tucker a screen test because of Tucker's photogenic good looks, thick wavy hair and height of six feet, five inches.
