Space drama Stargate Atlantis will conclude its run on Sci Fi Channel after the current, fifth season ends next January -- but the network has greenlit a two-hour Atlantis movie to run after that and says the show will live on as a network franchise.
After airing on Sci Fi sometime next year, the untitled Atlantis movie will be sold as a home-video title by producer MGM, Sci Fi told Multichannel News on Wednesday.
