Earth: Final Conflict is a Canadian science fiction television series based on story ideas created by Gene Roddenberry (the creator of Star Trek), and produced under the guidance of his widow, Majel Barrett-Roddenberry. It was not produced, filmed or broadcast until after his death. It ran for five seasons between October 6, 1997, and May 20, 2002.
The original title for the show was Battleground: Earth, but the producers changed it because it sounded too much like L. Ron Hubbard's novel, Battlefield Earth. The executive producer was Majel Barrett-Roddenberry. She also appeared in some early episodes as the character Dr Julianne Belman. Barrett was in possession of notes Roddenberry kept of story and series ideas; after his death, these notes provided the basis for this series.
Early in the 21st century, a race of aliens, the Taelons, arrive on Earth. In exchange for being allowed to take refuge on our planet, the Taelons offer the people of Earth access to their advanced technology. As a result, disease, war and pollution are nearly eliminated. Despite all these advances, there are some people who think the Taelons are not as benevolent as they seem. A resistance movement is organized.
Ultimately, it is discovered that the Taelon aliens are not purely evil, nor are they actually trying to "conquer" the world (except Zo'or, the main antagonist in seasons 2–4). They can no longer reproduce: Da'an was the last Taelon to have a child (Zo'or was the last child to be born but Zo'or is barren) and are on the verge of extinction. Their initial goal is to see if they can use humanity to extend their lives. However, they do have a hidden agenda: to bioengineer the human race to help fight their mortal enemy, the Jaridians (who are of Taelon origin). In doing so, they have no problem violating human civil liberties to reach their goals. The Jaridians believe that the Taelons' inability to reproduce is psychological.
The show was premiered on October 6, 1997 and ran for five seasons. The finale was broadcast on May 20, 2002. The show is famous for the unusually high turnover rate among the regular cast, partially due to contractual disagreements between the cast and the producers. Almost all of the show's major characters were killed or otherwise removed within a season or two of being introduced.
In fact, the only character to appear as a regular during all five seasons was FBI Agent Ronald Sandoval (Von Flores), the show's main antagonist. The fifth season of the show was a radical departure from the storyline of the previous seasons, with the Taelons being replaced by a new and more openly hostile alien race, a group of energy vampires called the Atavus.
The series was first shown on CTV in 1997 and ran for two seasons until the network decided to cancel it due to low ratings. The show was, however, resurrected by Chum Limited and was moved to their New Net network for the remainder of its run. The series was broadcast in syndication in the United States. The series has been re-shown daily on Bravo in the United Kingdom, Showcase in Canada, Jimmy in Italy, and Bangladesh Television in Bangladesh.
ADV Films released the third, fourth and fifth seasons on DVD in 2003 as these were the only seasons for which they had the distribution rights. On May 5, 2009, Universal Studios Home Entertainment released season 1 on DVD for the very first time. Alliance Home Entertainment has released all five seasons on DVD in Canada only.
Universal Pictures UK released the first season on DVD in the UK on April 3, 2006. Via Vision Entertainment has released all five seasons on DVD in Australia.
Spin-off and Possible Reboot:
The series finale hinted that a new show would evolve wherein Renee Palmer would travel through space seeking out other species that Earth can befriend, essentially the basis of Gene Roddenberry's Star Trek. But the proposed series never materialized. In 2009 there was talk that the CBC network were interested in rebooting the show. So far there is no word if such a project will happen. It probably will not ever see the light of day unfortunately.
