An intriguing movie from the cold war era (or rather, the first one), The 27th Day involves an alien from a dying planet giving five persons the ability to destroy human life on a massive scale. Is it a test? Is it a trick? Directed by William Asher, who did a lot of television-episode directing for I love Lucy and Bewitched, and a screenplay by John Mantley (author of the novel), who went on to write for Gunsmoke, The Wild Wild West, and Buck Rogers in the 25th Century, the story has themes of global destruction, communism, and political tensions that are still relevant today. William Asher also directed the AIP beach party films of the 1960s and a forgotten slasher called Butcher, Baker, Nightmare Maker 1981 (check out Moria for more information). The one shot of the alien spaceship interior is taken from Earth vs. The Flying Saucers (both that movie and this one were produced by Columbia).
