In 1997, Jonathan Glassner and Brad Wright co-developed Stargate SG-1, a television series intended to continue the story laid down by the original film. Although new actors were cast, several roles from the film were reprised, including the main characters Daniel Jackson and Jack O'Neill (which was re-spelled to include an extra "L"). The Stargate Command setting was transferred from a fictional military facility located in Creek Mountain, to the Cheyenne Mountain military complex. Other variations and differences between the original film and SG-1 mostly concern the location of the planet Abydos, the alien Ra, the race of Ra's underlings (Jaffa), and Stargate travel.
The series debuted on Showtime on July 27, 1997, and moved to the Sci-Fi Channel after its fifth season.It starred Richard Dean Anderson (as O'Neill) and Michael Shanks (as Jackson), alongside Amanda Tapping, Christopher Judge and Don S. Davis playing the new characters Samantha Carter, Teal'c and George Hammond. The cast remained fairly regular for most of SG-1's run, but experienced some changes. Michael Shanks left the show at the end of Season 5 and was replaced by Corin Nemec as Jonas Quinn. Shanks returned at the beginning of Season 7 and Nemec was written out. At the end of Season 7 Davis left the show and Anderson filled the gap he left in the story. Season 9 saw the departure of Anderson, but added new regulars Beau Bridges and Ben Browder. After a debut episode in Season 8, followed by appearances in eight episodes of Season 9, Claudia Black's popular reception earned her a position in the regular cast in Season 10.
MGM put an average of $1,400,000 into each episode of the show, and regards it as one of its most important franchises.Stargate was taken off air in 2007; however, two movies entitled Stargate: The Ark of Truth and Stargate: Continuum were made to tie up loose ends.
O'Neill (Richard Dean Anderson) was a main character in the first eight seasons of Stargate SG-1 (1997–2005). O'Neill had a recurring role in Stargate Atlantis for the first three seasons (2004–2007), and he also appeared in the 2008 direct-to-DVD SG-1 film Stargate: Continuum as a minor character. Anderson reduced his character's status in season six to spend more time with his family, eventually leaving the show after season eight, thereby removing himself from the status of main character.
Daniel Jackson, Ph.D, is a fictional character in the Canadian-American military science fiction television series Stargate SG-1. Daniel Jackson is first introduced in the 1994 film Stargate, and is played by James Spader. In the ensuing television series the character is played by Michael Shanks. Daniel Jackson is a civilian archeologist and linguist, who works with the Stargate military project and therefore holds no military ranking. After the kidnapping of his wife Sha're in "Children of the Gods", Jackson joins SG-1 to rescue her.
Teal'c is a fictional character in the military science fiction television series Stargate SG-1. Played by Christopher Judge, Teal'c is a Jaffa warrior from the planet Chulak. As a Jaffa, Teal'c has a human appearance but has an abdominal pouch that serves as an incubator for a larval Goa'uld. The larval symbiote grants enhanced strength, health, healing, and longevity; Teal'c is around 100 years old during the show's run and ages an additional 50 years in the final SG-1 episode. Teal'c's most notable feature is a golden tattoo on his forehead, a sign that he once served the System Lord Apophis as First Prime, the most senior Jaffa rank.
Samantha "Sam" Carter
Samantha "Sam" Carter is a fictional character in the Canadian-American military science fiction television series Stargate SG-1. Carter is played by an English-Canadian actress Amanda Tapping, Carter was a main character in all ten seasons of Stargate SG-1 (1997–2007). Following a recurring role in Stargate Atlantis for three seasons (2004–2007), Carter became a main character in season 4 of Atlantis (2007–2008), and also appeared in the 2008 direct-to-DVD SG-1 films Stargate: The Ark of Truth and Stargate: Continuum. Amanda Tapping accepted a starring role in Sanctuary and only appears in the first and last episodes in the fifth season of Atlantis (2008–2009)
Stargate SG-1 resumes the plot of the original feature film and follows the present-day adventures of SG-1, a military team from Earth. SG-1 and two dozen other SG teams venture to distant planets using a fictional alien portal known as a Stargate, which in the series is housed in a top-secret United States Air Force military base known as Stargate Command (SGC) underneath Cheyenne Mountain in Colorado Springs, Colorado. In the first eight seasons, the mission of the SG teams is to explore the galaxy and search for alien technology and allies to defend Earth against the Goa'uld, a snake-like parasitic alien race that takes humans as unwilling hosts. As explained in the series' backstory, the Goa'uld transported human slaves from Earth to other habitable planets across the galaxy thousands of years ago and now pose as gods of Ancient Earth mythologies, particularly Egyptian mythology. SG-1 eventually learns that highly evolved but now impassive human-like beings, known as the Ancients, had originally built the Stargate network millions of years earlier, before they used their extraordinary powers to Ascend to a higher plane of existence. The fictional Ori, who belong to the same race as the Ancients but preach religious fundamentalism, assume the role of the main antagonists in seasons 9 and 10.
