Killers from Space (also known as The Man Who Saved the Earth) is a 1954 American independent science fiction film produced and directed by W. Lee Wilder, and starring Peter Graves, Barbara Bestar, Frank Gerstle, James Seay, and Steve Pendleton.

[2] Lee Wilder's production company, Planet Filmplays, usually producing on a financing-for-distribution basis for United Artists, wound up making this film for RKO Radio Pictures distribution.

While collecting aerial data on a United States Air Force (USAF) atomic blast at Soledad Flats, the pilot loses control of their aircraft and they crash.

Deep under the drug's influence, Martin tells a story about being held captive by space aliens, led by Denab, in their underground base.

The aliens plan to exterminate humanity using giant insects and reptiles, grown with the radiation absorbed from our own atomic bomb tests.

With calculations made using a slide rule, Martin determines that if he shuts off the power to Soledad Flats for just 10 seconds, it will create an overload in the aliens' equipment.

In 2006, film reviewer Thomas Scalzo also noted: "Killers From Space is an enjoyable, if slow-going, sci-fi / horror diversion, and if these killers from space had somehow found a way to stop their yammering long enough to get on with some actual killing, the combination of Peter Graves, mutant insects and amphibians, a palpable atmosphere of ’50s atomic fear, and the directorial efforts of Billy Wilder’s brother, would have been enough to bump the film into the upper echelon of early sci-fi essentials".
