Roads not taken – unmade Science Fiction films & television…
Plans were made to continue Stargate: SG-1 as a movie (or a series of movies).
[The following may contain brief spoilers for Stargate: SG-1.]
In 1994 Roland Emmerich and Dean Devlin’s movie Stargate was release. envisioned by them as the first in a trilogy, but instead lead to the 1997 TV continuation Stargate: SG-1 which went for 10 years and had two spin-off series. After SG-1 ended two direct-to-DVD movies were made Stargate: The Ark of Truth (2008) and Stargate: Continuum (2008) continuing the series. Plans were made for more direct-to-DVD movies, starting with one for the spin-off Stargate: Atlantis (Stargate: Extinction) and one for SG-1…
The film was going to center on the character of Jack O’Neill (Richard Dean Anderson), bringing him back to the center of the Stargate story. A scene showing that Samantha Carter (Amanda Tapping) and Jack were now together. It was also hinted that the population at large would learn of the stargates and that there would be a large space battle (possibly including the moonbase.)
Along with Jack and Sam, Daniel Jackson (Michael Shanks) and Teal’c (Christopher Judge) were set to return, while new cast Cameron Mitchell (Ben Browder), Hank Landry (Beau Bridges) and Vala Mal Doran (Claudia Black) would not. Browder and Bridges were not approached, and the character of Vala was stated to not appear in the film.
The script was written, but after the failure of the last spin-off series Stargate: Universe, it signaled the end of the Stargate TV franchise. Creators of the original film Roland Emmerich and Dean Devlin have since declared their intention of completely the trilogy they originally intended by remaking the original film.
Well, umm, nothing. The while Stargate: Extinction was suggested as a comic from Boom Studios (although it didn’t appear), no such suggestion was made for Stargate: Revolution.
