A down-and-out traveller discovers a pair of sunglasses which let him see through the illusions aliens have been using to control mankind.
With overtones of the manipulation of the everyman, I would easily put this movie in the same class as Nineteen Eighty-Four. However, the otherwise weighty impact is cushioned by comedy, great characters and a great story. Though old, this movie stands the test of time. Easily considered satirical-horror, there's much more to it.
