Stargate SG-1

Stargate SG-1 (sometimes written Stargåte to mimic the title art, and popularly abbreviated as SG-1) is a television series based upon the 1994 science fiction film Stargate. more...

The premise of both is the existence of devices called Stargates, which allow travellers to cross the vast distances of space in an instant. The show focuses on a team called SG-1, who, in the top-secret U.S. military base called the SGC hidden underneath Cheyenne Mountain, use the Stargate found on Earth to explore other worlds and defend Earth against alien threats. Thus unlike many other science-fiction franchises with an interplanetary-exploration theme, SG-1 is set in the present day, is based on Earth, and primarily involves humans.

The series is produced by MGM and filmed in Vancouver, British Columbia, Canada. The first episode was broadcast on July 27, 1997 on Showtime, which aired the series' first five seasons. Since season six, the show is aired on the Sci Fi Channel. In October 2005, the Sci Fi Channel renewed SG-1 for a tenth season, making it the longest-running science fiction series on American television, surpassing The X Files's nine seasons and 202 episodes.

Developed for television by Jonathan Glassner and Brad Wright, SG-1 originally starred Richard Dean Anderson, Michael Shanks, Amanda Tapping, Christopher Judge and Don S. Davis. The cast would change in later seasons. Actor Corin Nemec was a regular during the 6th Season, replacing Shanks. Shanks would return in Season 7 (often attributed to fan demand), replacing Nemec. Davis left as a regular during the eighth season, and Anderson in the ninth; the latter season added new regulars Ben Browder and Beau Bridges. For Season 10, Claudia Black will be added as a new regular, reprising her recurring role as Vala Mal Doran.
