They Live

From Wikepedia...
They Live is a 1988 science fiction/horror film directed by John Carpenter, who also wrote the screenplay under the pseudonym Frank Armitage (this is the name of one of the characters in the movie). Part science fiction horror and part dark comedy, the film echoed contemporary fears of a declining economy, within a culture of greed and conspicuous consumption common among Americans in the 1980s. In They Live, the ruling class within the moneyed elite are in fact aliens managing human social affairs through the use of a signal on top of the TV broadcast that is concealing their appearance and subliminal messages in mass media.

Carpenter is on record as attributing the film's initial commercial failure to result from an audience "[those] who go to the movies in vast numbers these days don't want to be enlightened". Fast forward to 2011, and you may realize that it applies even more so today!
