<Li> Robert "Buzz" Henry as Posseman (uncredited) </Li> <P> The screenplay by Harry Essex, with input by Jack Arnold, was derived from an original and lengthy screen treatment by Ray Bradbury; screen legend says that Bradbury wrote the screenplay and Harry Essex merely changed the dialogue and took the credit . Unusual among science fiction films of the era, the alien "invaders" were portrayed by Bradbury as creatures stranded on Earth and without malicious intent toward humanity . The film can be interpreted as a metaphorical refutation of the supposedly xenophobic attitudes and ideology of the Cold War . Bradbury said "I wanted to treat the invaders as beings who were not dangerous, and that was very unusual". He offered two story outlines to the studio, one with malicious aliens, the other with benign aliens . "The studio picked the right concept, and I stayed on". In 2004 Bradbury published in one volume all four versions of his screen treatment for It Came From Outer Space . </P> <P> Filming took place on location in and around the California towns of Palmdale, Victorville, and the Mojave Desert, as well as on Universal's sound stages . </P> <P> The film's uncredited music score was composed by Irving Gertz, Henry Mancini, and Herman Stein . </P>
