"Stargate Atlantis" was a spin-off television series from "Stargate SG-1". A new feature film was originally intended to transition the two series after the sixth season of "SG-1". Later, "SG-1" was renewed for a seventh season, and the feature film was then planned to transition that season. Finally, when "SG-1" was renewed for an eighth season, the intended film instead became the two-part season finale episode "Lost City", and the setting of "Stargate Atlantis" was moved to the Pegasus galaxy. This allowed the two shows to exist side-by-side within the same fictional universe, and later the two shows even become interconnected. "Atlantis" was developed by most of the same people and in the same studios as "SG-1".
