Like most of Robert Wise’s work, this slickly constructed 1951 science fiction film settles squarely in the middle of its genre, better than some and worse than others, though Michael Rennie was born to play the sleekly tailored visitor from another planet who carries a warning message to earth. The picture is smooth and atmospheric, but it nowhere finds the knife-edge of its famous contemporary, Don Siegel’s Invasion of the Body Snatchers. With Patricia Neal and Hugh Marlowe (who was doomed to play the same part for the next decade). The evocative score is by Bernard Herrmann.
