20th Century Fox is developing a reboot of the 1988 sci-fi movie Alien Nation, with Iron Man writers Art Marcum and Matt Holloway coming aboard to write the screenplay. The project doesn't have a producer on board at this stage. The studio is envisioning a re-imagining of the original movie, with the hopes of starting a franchise similar to their rebooted Planet of the Apes movies.

The original Alien Nation was set in a future where humans and an alien race were forced to co-exist with each other, as the humans keep the alien species segregated from the general population with very little rights. The plot followed the first ever alien police officer (Mandy Patinkin) on Earth, who is paired up with a racially-biased cop (James Caan). Although they have their differences, a case comes up that causes them to form a mutual respect for one another. The original movie spawned a short-lived TV series and a number of TV movies such as Alien Nation: Dark Horizon, Alien Nation: Body and Soul, Alien Nation: Millennium, Alien Nation: The Enemy Within and Alien Nation: The Udara Legacy, along with novels and comic books.

While no extensive plot details were given, the Alien Nation reboot will begin by explaining why the aliens came to Earth. The original movie was produced by Gale Anne Hurd, who now serves as an executive producer on AMC's highly-successful zombie series The Walking Dead. Art Marcum and Matt Holloway have recently written the Highlander and Buck Rogers reboots that are currently in development. Their other writing credits include Shadow of Fear and Punisher: War Zone.
