it was originally a movie that came out in 1994, with Kurt Russel and James Spader....then a tv show in 1997 with Richard Dean Anderson, Michael Shankes, Amanda Tapping, and Christopher Judge, and the tv show called Stargate SG-1 is still going....the 9th season will start in July probably....there is also a new stargate show called Stargate Atlantis...anyway SG-1 is about a group of people who explore other planets in the galaxy through a worm hole device known as the Stargate....heh....there should be some info on scifi.com...it is a cool show, they are even making a video game of it that should come out in the fall of this year...heh
...these explorers, of course the stargate program is run by the military...two of the four people of the sg-1 team are military, one is an archaeologist, and the fourth is an alien, of the race Jaffa, who once served the aliens known as the Goa'uld, who are Earths main enemy...so yeah....there's Jack O'Neil, Samantha Carter, Daniel Jackson, and the alien's name is T'ealc...it is a cool show...one of my favorites...that and Smallvile hah...but I really love star wars so much now that I am starting to get less interested in some of the other shows I watch hah....
