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".
