Stargate: SG-1

With its recently announced upcoming ninth season, this series is tied with "The X-Files" (1993) as the longest running science-fiction series on American television.

The Oval Office set used for the show is the same one used in the motion picture X2 (2003).

The prop used to portray the device which controls the Tok'ra memory recall device which looks like a "wand" is actually an electric nose hair trimmer and is used unaltered

Christopher Judge (Teal'c) has only appeared without his character's trademark gold emblem in three episodes: "The Gamekeeper", "2010" and "The Changeling.

The on-set stargate prop is made out of plastic.

The character 'Jack O'Neill' was ranked #10 in TV Guide's list of the "25 Greatest Sci-Fi Legends" (1 August 2004 issue).

Stargate SG-1 is officially endorsed and supported by the United States Air Force - the only current show with that seal of approval.
