About Stargate Atlantis

Stargate Atlantis, often abbreviated as SGA, is a Canadian-American military science fiction television series and part of MGM’s Stargate franchise. The show was created by Brad Wright and Robert C. Cooper, as a spin-off series of Stargate SG-1 created by Wright and Jonathan Glassner after the release of Stargate (1994). The first three seasons of the television series were broadcast by Sci Fi Channel and The Movie Network before the series moved only to Sci Fi Channel for its last two seasons, meaning a release of 100 episodes before the series was cancelled. Stargate Atlantis premiered on Sci Fi Channel on July 16, 2004; its final episode premiered on Sci Fi Channel on January 9, 2009. The television series was filmed in and around Vancouver, Canada.

The story of Stargate Atlantis follows the cliffhanger episode on Stargate SG-1’s seventh season finale “Lost City”, where SG-1 found an outpost made by the race known as the Ancients in Antarctica. After the events of Stargate SG-1 season eight premiere “New Order”, the Stargate Command sends an international team to investigate the outpost. Soon, Dr. Daniel Jackson discovers the location of the greatest city created by the Ancients, Atlantis. The story unfolds when the members of the expedition encounter the Wraith, the race that defeated the Ancients ten thousand years ago.

The series was a ratings success for the Sci Fi Channel, and was particularly popular in Europe and Australia. Although it received little critical response, Stargate Atlantis was honored with numerous awards and award nominations in its five-season run. After Stargate Atlantis was cancelled, the show’s co-creators began working on the already conceptualized Stargate Universe which the network had approved to have a bigger budget, be less mythology dependent, and have more focus on character development. Stargate Universe was released on October 2, 2009. Merchandise for Stargate Atlantis includes games and toys, print media and an original audio series. A direct-to-DVD film entitled Stargate: Extinction is planned to be released.
