Oscar Godbout of "The New York Times" reviewed the film strictly as entertainment for youngsters, calling it "a pictorial 'funnybook'" that would "probably frighten witless a lot of small children". A generally positive review in "Variety" wrote: "Imaginative yarn makes full use of astronomical and lab equipment as well as Government atomic research installations as backgrounds to heighten the realism. Highlight, however, is a Martian ray gun which can cause the earth to part into subterranean passages. All this has been effectively filmed by John Seitz in Cinecolor". "Harrison's Reports" declared it "A pretty good science-fiction melodrama, photographed in Cinecolor. The story, as in most pictures of this type, is highly imaginative, but it is packed with suspense from start to finish and should thrill the action fans, especially the youngsters".
