‘Stargate Atlantis’ Ends Sci Fi First Run After Season 5

2-Hour TV-Movie Greenlit For 2009 As Stargate Franchise Lives On In Features

By Kent Gibbons -- Multichannel News, 8/20/2008 5:59:00 PM

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.

MGM this year released two financially successful straight-to-DVD movies made after progenitor series Stargate SG-1 ended a 10-year run of first-run cable episodes on Sci Fi. MGM and the show producers are scheduled to make more in DVDs in future. A movie franchise is also envisioned for Stargate Atlantis.

Meanwhile, we get a two-hour movie instead of 20 hours. I can't say I'm all that thrilled that Mallozzi and partner will pen the movie.

Sigh. This sucks. Feel free to rant in the comments section.
