Don your green-and-red glasses for this science fiction classic, based on a story by Ray Bradbury, in which a spaceship crash-lands near a small town in the Arizona desert. As residents begin to disappear, it dawns on their neighbors that the aliens have been adopting the identities of the townspeople, and a posse is formed to destroy the invaders. In depicting the unearthly visitors as more benign than the earthlings they encounter, the film provides a gentle rejoinder to the xenophobia that reigned in the cinema of the Cold War era.
