Stargate: Continuum is a Canadian-American military science fiction direct-to-DVD film released through MGM Home Entertainment (MHE), written by Brad Wright and directed by Martin Wood. The film is a time-travel adventure and is the second sequel to Stargate SG-1, after Stargate: The Ark of Truth. The film features the season 10 cast of Stargate SG-1 and Richard Dean Anderson (Seasons 1–8). It was filmed in early 2007 at Vancouver's Bridge Studios and in the Arctic. The story arc follows SG-1 in their mission to re-instate the original timeline changed by Ba'al by infiltrating the ship, Achilles.

While SG-1 and Jack O'Neill attends the extraction ceremony of the last Goa'uld System Lord. Ba'al comes up with an ominous warning, he explains he has a contingency plan in the event something like this ever happened. In the meantime, the real Ba'al travels back in time to 1939, to create an alternate timeline in which Earth never found their Stargate. He then, using the knowledge gained in the original timeline, takes control of the Goa'uld Empire.

The film has garnered positive reviews in initial critical reception compared to the previous film, Stargate: The Ark of Truth, earning both praise and criticism for its atmosphere, story, characters, and graphic content. The production budget was US$7 million and the film grossed over US$8 million USD, less than the previous film that grossed over US$13 million. The film was released on both DVD and Blu-ray Disc in the US on July 29, 2008 and elsewhere in August 2008, followed by a TV premiere on Sci-Fi channel on April 3rd, 2009.
