"The SCI FI Channel is ending Stargate Atlantis after five seasons, Multichannel News reports. 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."
I've not been paying attention lately. This was announced about 2 weeks ago. Oh well, I knew it would happen eventually. When the original show was canned, Atlantis had maybe 2-3 more at most I'd thought.
