the franchiseWhile working on Independence Day, Dean Devlin and Roland Emmerich sold the rights to Stargate to MGM who hired Brad Wright and Jonathan Glassner to develop a television programme based on the movie. This television programme, Stargate SG-1, would run for ten years and spawn three television spin-offs and a range of books, merchandise and games.
stargate sg-1Running from 1997 to 2007, Stargate SG-1 was based on the Stargate movie, but several changes were made to the characters and storyline to allow for the development of an ongoing television programme.
- Kurt Russell was replaced by Richard Dean Anderson. Several changes were made to the character of O'Neil including his rank (Colonel in the movie, Lieutenant Colonel in the programme), the spelling of his name (O'Neil in the movie, O'Neill in the programme) and his character (serious and humourless in the movie, irreverant and unconventional in the programme).
- James Spader was replaced by Michael Shanks as Daniel Jackson.
- John Diehl was replaced by Jay Acovone as Charles Kawalsky. Kawalsky's rank was also changed from Lieutenant Colonel to Major.
- French Stewart was replaced by Brent Stait as Louis Feretti. The spelling of Feretti's name was changed to Ferretti.
- Mili Avital was replaced by Vaitiare Bandera as Sha'uri, now spelt Sha're.
- Sara O'Neil became Sarah O'Neill.
- Tyler O'Neil became Charlie O'Neill.
- Stargate Command moved from a fictional facility in Creek Mountain, to the real Cheyenne Mountain complex.
- The location of Abydos (which was not named in the movie but was in the novelisations and merchadise) was changed from the Kalium galaxy to the Milky War galaxy.
- The Abydos Stargate was no longer the only address that could be dialled from Earth.
- The Stargate symbols were changed to incorporate a point of origin symbol.
- The freezing temperatures which accompanied travel through the Stargate were eventually dropped.
- Although Ra was the last of an unnamed race in the movie, he is now just one of several Goa'uld System Lords.
