Alien Nation was a science fiction television series, loosely based on the movie of the same name that had its original 22 episode run from September 18, 1989 – May 7, 1990. Gary Graham starred as Detective Matthew Sikes, an LA police officer working with “Newcomer” alien George Francisco (Eric Pierpoint) on assorted cases usually related to the arrival of George’s species to Earth.
The show might have been ripe with Science Fiction possibilities, but the stories were more grounded and tended to me more like morality plays. So the strange circumstance of having an alien species cohabitating with humans, is not a vital part of the show, although the cultural difference are often the crux of some stories. At its heart the show was a classic mismatched buddy cop show.
