Stargate: Continuum

Stargate: Continuum is a 2008 American military science fiction film directed by Martin Wood and written by Brad Wright. It is the second sequel to the television series Stargate SG-1, following The Ark of Truth (2008). The film stars the main cast of the series' last season, with the return of Richard Dean Anderson as Jack O'Neill. The film is a time-travel adventure in which Ba'al travels back to 1939 to create an alternate timeline in which Earth never establishes their Stargate Program, and to take control of the Goa'uld Empire. As the only people to remember the truth, the SG-1 team attempts to reinstate the original timeline. Continuum was released direct-to-video on July 29, 2008, by MGM Home Entertainment (distributed by Fox). The Sci-Fi Channel premiered the film on television in the United States on April 3, 2009.
