the production of two direct-to-DVD films in October 2006, and Amanda Tapping joined the Atlantis cast for their fourth season. The first film, Stargate: The Ark of Truth, was released in March 2008 and wraps up the Ori storyline. The second film, Stargate: Continuum, is an alternate time-line time travel story and was released in July 2008. A special edition of the two-hour pilot episode "Children of the Gods" with re-edited scenes and a different score has also been produced. In April 2009, MGM confirmed a third new SG-1 film that Brad Wright had first announced in May 2008. Joseph Mallozzi revealed the working title as Stargate: Revolution.

By then, neither the Atlantis nor Universe television series were produced anymore. Still, Wright did not rule out future Stargate films, saying; "It's a franchise. Stargate is not over. Somebody smart from MGM is going to figure it out and something will happen." Home media Stargate SG-1 was first released on DVD in some European nations in volumes of typically four episodes each, beginning with "The
