How many seasons did Stargate SG-1 last and is there any hope for a revival? Blockbuster auteur Roland Emmerich scored his first major hit with 1994's Stargate, where a team of soldiers and James Spader's nerdy but hunky scientist travel through the titular gate to another world. The movie was set to become a trilogy but Emmerich became busy on other projects, and instead the franchise continued in the form of Stargate SG-1. This continued the story set up in the film, with Spader and co-star Kurt Russell replaced by Michael Shanks and Richard Dean Anderson respectively.
Amanda Tapping and Christopher Judge rounded out Stargate SG-1's team. The show did a good job of expanding and building upon the mythology of the film, and it was fronted by a likable cast of characters with Anderson, in particular, bringing a delightfully snarky edge to his role. It became a robust ratings success too, leading to something of a franchise. The first spinoff was Stargate: Atlantis, which ran for five seasons and featured an early leading role for Jason Momoa. Stargate: Universe was pitched as something of a darker spin of the concept but only lasted two seasons, and was cancelled on a cliffhanger.
Stargate SG-1 wrapped up in 2007 after ten seasons and over 200 episodes. The storyline continued for two STV movies in 2008, Stargate: The Ark of Truth and Continuum, but while there were plans for a third, it was later cancelled due to MGM's financial difficulties at the time. Richard Dean Anderson left the main cast of SG-1 around season 8 to spend more time with his daughter, though the character made guest appearances in later series. The third movie was set to focus on his character O'Neill, making its cancellation doubly disappointing.
Stargate SG-1 ended over a decade ago and the franchise itself has been dormant for many years. While fans long for a revival of either SG-1 or a new movie or TV show, there don't appear to be any plans for more presently. Richard Dean Anderson and Amanda Tapping have confirmed they'd be up for more adventures, possibly in the shape of a TV movie or miniseries, but while MGM is apparently mulling some kind of reboot, nothing is set in stone.
Stargate SG-1 was a big hit during its ten season run so interest in a revival remains high. The franchise was good to MGM so it's unlikely it will remain in purgatory forever, but whether or not its next incarnation takes the form of a Stargate SG-1 revival or something else remains to be seen. The cast at least seems open to it, so the ball is in MGM's court.
