Video games Two video games based on the film were published by
Acclaim Entertainment: a
1995 side-scrolling platform game for the
Super Nintendo Entertainment System and
Sega Genesis, and a
Tetris-like
puzzle video game for the
Game Gear and
Game Boy.
Cancelled film sequels Devlin and Emmerich always envisioned
Stargate as the first part of a
trilogy of films, but Parts 2 and 3 were never developed. At Comic-Con 2006, twelve years after the original film was released, Devlin stated that he was in early discussions with rights-holders MGM about finally bringing the final two parts to the screen. According to Devlin, the second film is intended to be set around twelve years after the original, with Jackson making a discovery that leads him back to Earth and to the uncovering of a new Stargate. The second entry would supposedly use a different mythology from the Egyptian one which formed the background to the original film, with the third installment tying these together to reveal that "all mythologies are actually tied together with a common thread that we haven't recognized before." Devlin stated that he hoped to enlist original stars Kurt Russell (Col. Jack O'Neil) and James Spader (Dr. Daniel Jackson) for the sequels. The actors reportedly expressed an interest in participating in the project. The film trilogy would not directly tie into the series
Stargate SG-1. According to Devlin, the relationship between the movie and the series is "we would just continue the mythology of the movie and finish that out. I think the series could still live on at the end of the third sequel. So we're going to try to not tread on their stories."
Novel series Using some of Emmerich's notes,
Bill McCay wrote a
series of five novels, continuing the story the original creators had envisioned, which involved the Earth-humans, the locals and the successors of Ra.
Television spin-offs The CD-ROM programme
Secrets of Stargate, released after the film, showed how the special effects were made, and included behind-the-scenes of the film and the showing of interviews with the cast and the production members. Dean Devlin eventually gave
Metro-Goldwyn-Mayer (MGM) the rights over the film. In 1996, MGM hired
Brad Wright and
Jonathan Glassner to create a
spin-off television series.
Stargate SG-1 premiered on the American subscription channel
Showtime on July 27, 1997 and ended its ten-season run in 2007.
Stargate SG-1 itself spawned the non-canon animated television series
Stargate Infinity (2002–03), and the live-action television series
Stargate Atlantis (2004–09) and
Stargate Universe (2009–11).
Differences from film to television franchise SG-1 creators and executive producers Brad Wright and Jonathan Glassner altered the canon by introducing several new concepts during production of the
SG-1 and
Atlantis series. In the television series, characters were portrayed by different actors, and names were spelled differently.
French Stewart's character was Lieutenant Louis Ferretti but in
SG-1, played by
Brent Stait, he is a Major. The spelling of Daniel Jackson's wife changes from "Sha'uri" to "Sha're", O'Neill's wife from Sarah to Sara. (Similarly, the name of O'Neil's son changes from "Tyler" in the film to "Charlie".) The
Stargate Command setting was transferred from the fictional military facility located in Creek Mountain, to the
Cheyenne Mountain military complex. There were also changes to the Stargate. The unique set of 39 Stargate symbols in the film was replaced with the concept of 38 symbols that are the same for each Stargate (Earth's symbols based on Earth's constellations), plus a single point of origin symbol that is unique to that individual gate. on the television series this effect was completely created in
computer graphics by the Canadian
visual effects company
Rainmaker. At the beginning of
SG-1 season 9, the original wormhole-traversal sequence used in the film, and in the series up to that point, was replaced with a new sequence similar to the one already used on
Stargate Atlantis, but blue as it was in the movie and
SG-1. In
Atlantis, it is green, and in
Universe, it is white.
Reboot On September 5, 2013, during an interview with
Digital Spy, Emmerich said that he and MGM are planning a new
Stargate as a reboot with a trilogy. On May 29, 2014, it was announced that MGM and
Warner Bros. are partnering together for a reboot as a trilogy with Emmerich directing, Devlin producing, and Nicolas Wright and James A. Woods writing. On November 17, 2016, Devlin told
Empire Online that the plans to make a reboot and a potential new series are stalled. On April 14, 2023, it was announced that MGM were rebooting their film franchises for film and television, including
Stargate.{{cite web|url=https://deadline.com/2023/04/robocop-stargate-legally-blonde-barbershop-in-works-film-tv-amazon-mgm-ip-1235243057/|title='Robocop,' 'Stargate', 'Legally Blonde' & 'Barbershop' Among Titles In Works For Film & TV As Amazon Looks To Supercharge MGM IP|first1=Nellie|last1=Andreeva|first2=Peter|last2=White ==See also==
