AllMovie

Alien Nation: Dark Horizon is a television film made as a continuation of the Alien Nation television series. Produced by the Fox Network, Alien Nation lasted a single season, ending in 1990 with a cliffhanger series finale. Dark Horizon was written to be the season opener for the second season, but when the series was unexpectedly canceled and looked like it might never return to television, the plot was published as a book. Finally, four years later, Alien Nation: Dark Horizon appeared as a television film to pick up where the television series left off.
