The Cyclops is a 1957 science fiction horror film written, produced and directed by Bert I. Gordon, starring James Craig, Lon Chaney Jr. and Gloria Talbott. The theme of a monster created as a result of radioactivity was a common one in the 1950s. Plot Test pilot Bruce Barton is missing and his girlfriend, Susan Winter, organizes a search party, which is sent out in the jungles of Mexico. The team of scientist Russ Bradford, mining expert Martin "Marty" Melville, and pilot Lee Brand fly into unknown territory. While searching the area, however, they uncover giant mutated Earth animals such as a mouse, an eagle, a mygale, a green iguana, a tegu and a boa. More importantly, they encounter a mutated 25-ft tall, one-eyed human monster who became disfigured due to an exposure to radioactivity from massive radium deposits in the area. This is responsible for the unusual size of all the other giant inhabitants of the region. He kills Melville, but appears to recognize the girl. When the cyclops tries to prevent the rest of the group from flying to safety, he is wounded and presumably dies.

The producer/director worked feverishly to complete the film before money ran out, with only five or six days allotted to shooting. Not making things any easier was having to contend with Lon Chaney Jr. who was habitually drunk. Duncan Parkin also played Col. Manning in the War of the Colossal Beast (1958), the sequel to The Amazing Colossal Man (1957), basically playing the same disfigured giant in both films. Production effects in The Cyclops were limited to backscreen projection, rudimentary matte work, and incorporating large images into the scenes. In the film, there is a scene in which the creature grabs Susan, but he also grabs the background as well, revealing the black color behind it. The discovery of
