Richard Dean Anderson, former star and executive producer of Stargate SG-1, returns to the series for its historic 200th original episode. Production on the bi-centennial will commence on April 5 in Vancouver. Anderson, who will be reprising his role as General Jack O'Neill, will also make special guest appearances in a number of additional episodes of bothStargate SG-1 and Stargate Atlantis that will air in the new seasons. Both SCI FI Channel original series are slated to premiere this summer.

Stargate SG-1's 200th episode, appropriately titled "200," will center on the SG-1 team as they serve as advisors on a television series that bears remarkable similarities to the goings on at Stargate Command. As they pitch to the producer the many adventures that they have been involved with over the years, the team discovers that truth really is stranger than fiction...but nothing is stranger than the machinations of Hollywood. In addition to Anderson, 200 will feature a guest appearance by fan favorite Willie Garson (Sex & the City).

Currently in production on its tenth original season (its fifth on SCI FI), Stargate SG-1 is now the longest-running sci-fi series on American television, surpassing The X-Files and every iteration of Star Trek. Averaging more than 2.2 million viewers per episode the show is stronger than ever and has led SCI FI Channel to become the #1 cable destination on Friday nights for young adults.

Executive produced by Robert C. Cooper and co-creator Brad Wright, Stargate SG-1 centers on the Stargate, an ancient portal that allows instantaneous travel across the galaxy. The series stars Ben Browder, Amanda Tapping, Christopher Judge, Michael Shanks, Claudia Black and Beau Bridges.

Stargate SG-1 is produced by Double Secret Productions, in association with Metro-Goldwyn-Mayer Inc. and Sony Pictures Television.
