The SCI FI Channel is ending Stargate Atlantis after five seasons.
The show will go on, though, with a 2-hour movie that will air on SCI FI in 2009, and be released on DVD by MGM. The film will be written by executive producers Joseph Mallozzi and Paul Mullie.

It's intended to be the first of an on-going series of Atlantis movies, according to the report. Stargate SG-1 has released two very successful movies direct-to-DVD this year (Stargate: The Ark of Truth and Stargate: Continuum), though neither has aired on U.S. television yet.

There will be another Stargate series starting off soon called Stargate Universe.
