 Universal's make-up department submitted two alien designs to studio executives for consideration; the rejected design was saved and later used as the "Metaluna Mutant" in Universal's 1955 science fiction film "This Island Earth".The fiery special effects created for the crashing alien spacecraft consisted of a wire-mounted iron ball with dorsal fin, which had hollowed out "windows" all around for the burning magnesium inside.The Arizona setting and the alien abduction of telephone lineman and two other characters are fictionalized story elements taken from Bradbury's younger life when his father moved the family to Tucson, where he worked as a telephone lineman.
