Babylon 1 is an Australian/American science-fiction-fantasy television series created by Jason Holt of Hunters, starring Christopher Heyerdahl, Eliza Dushku, Eddie McClintock, and Brea Grant. It ran from June 14, 2007 until June 12, 2011, for a total of five seasons. The shows' first season aired on June 14, 2007, and was renewed for a second season. The second series aired on August 3, 2008 on Sci-Fi, returning to its 9:30 PM slot-time. It was renewed for a third season for 2009, and aired on July 2, 2009 at 9:30 PM, holding its same slot-time since 2007.

Following the well-received third season, Sci-Fi commissioned the show for a fourth season, which, according to creators, will end in a two-hour movie. Jason Holt has said that 2010 will see the sixth and final season of Hunters (TV series) and a major concentration on Babylon 1 and its fourth season. The fourth season aired on May 4, 2010, and the first part of the series finale aired on July 3, 2010. The fourth series concluded on July 11, 2010, and rumours of either a fifth season or feature length film circulated. A three part mini-series, titled Babylon 1: Stoker Chronicles aired between April 5–19, 2008, detailing Stoker's activities before the events of season one.

The show was renewed for a fifth season, and the first episode aired on March 20, 2011, with the entire cast and crew returning. The final episode of the fifth season aired on June 12, 2011. It was announced the day before that it would be the series finale.


After the success of Jason Holt and Renon Schaefer's TV series Hunters, they began production of a new show in early 2007. Holt had penned a script whilst working on Hunter's second season, originally titled Babylonia. The two opted the script to producers, but it underwent several changes before becoming the initial pilot of Babylon 1. Christopher Heyerdahl received a script from the creators, who were impressed by his previous roles. Tony Curry, from such roles as Underworld: Evolution, was also opted for the role of Dr. Jacob Harker. Actor Eddie McClintock went for the role of Luke Cosgrove, but creators felt he was suited to Dominic Williams. He was the first to be cast in the show, and Christopher Heyerdahl was cast in the main role as Jacob Harker. The role of Amanda went through several actresses, until Eliza Dushku was finally cast.

Plot summary

Babylon 1 follows the exploits of Dr. Jacob Harker, and his team (his assistant and head science officer Amanda Smith, head of security and computers Luke Cosgrove, head of medical Dominic Williams, his niece Claire Cambridge and the Supernatural Brayanir) in their effort to further study the rift between Earth and the world of the Supernaturals, without alerting the enemy or the public. Twenty years earlier Jacob worked with his former assosciate James Stoker in an effort to find the rift, but they parted ways. Stoker returns in season one eager for revenge, because Harker did not share his discovery with James Stoker. After Harker kills him he is presumed dead, but in season two he returns after injecting himself with the blood of Supernatural that can resurrect itself, and kills Claire's parents. After a confrontation between Harker and Stoker, Stoker is killed again, and Harker sacrifices himself to protect Earth and Earth 2. His daughter Alice takes control of Babylon 1's operation, until in season three the team resurrect Harker. The third season also introduces Harker's former mentor, and later revealed father, Charles Starkley. Season three results in a climactic battle between Harker and his father, ending in Starkley's eventual suicide.
