The Deadly Mantis is a 1957 American science fiction monster film produced by William Alland for Universal-International. The film was directed by Nathan Juran from a screenplay by Martin Berkeley based on a story by producer William Alland. The Deadly Mantis stars Craig Stevens, William Hopper, Alix Talton and Pat Conway. Plot In the South Seas, a volcano explodes, causing North Pole icebergs to shift. A 200-foot-long praying mantis, trapped in the ice for millions of years, stirs. The personnel at Red Eagle One, a military station in northern Canada that monitors the Distant Early Warning Line, realize that the men at one of their outposts are not responding to calls. Commanding officer Col. Joe Parkman flies there to investigate, and finds the post destroyed, its men gone, and giant slashes left in the snow outside. Joe sends his pilots out to investigate when a radar blip is sighted, but their target disappears. An Air Force plane is attacked by the mantis. Joe searches the wreckage and, in addition to the huge slashes, finds a five-foot-long spur in the snow. He takes it to General Mark Ford at the Continental Air Defense (CONAD) in Colorado Springs, Colorado. Ford gathers top scientists, including Professor Anton Gunther, to examine the object.

After examining the object, Ned recognizes it as a torn-off spur from an insect's leg, and narrows it down to a gigantic praying mantis. In the Arctic, the mantis attacks an Inuit village. Ned is sent to Red Eagle One to investigate further. Museum magazine editor Marge Blaine gets permission to accompany him as his photographer. All the men at the base, including Joe, are smitten by Marge. That night, Marge and Joe join Ned in his office and discuss the mantis. The mantis attacks the building. Although the full unit opens fire on the mantis with automatic rifles and a flame-thrower, it is unscathed and moves away only after aircraft encircle it. Hours later, the base remains on red alert. The mantis attacks a boat off the Canadian coast, which means that it is flying at a speed of 200 miles an hour. Ford calls a press conference to announce the mantis's existence and ask the Ground Observer Corps to track its whereabouts. Over the next few days, Ned, Marge,
