The third version, used on the Syfy Channel, was similar to the first but focused on an activating Stargate and concluded with SG-1, seen from behind, entering the Stargate. The fourth version, appearing in the first half of Season 9, depicted a Stargate floating in space, SG-1 walking toward it at the SGC, and the camera traveling through the active Stargate.

15. The series was initially intended to conclude after seven seasons with a feature film serving as its finale.

16. Stargate SG-1 was known for its occasional self-referential humor. Notably, the 100th episode (Wormhole X-Treme! (2001)) and the 200th episode (200 (2006)) featured storylines filled with self-aware moments and numerous in-jokes.

MGM president John Symes approved the project on the condition that Wright and Glassner work together as executive producers.

21. Symes reached out to Michael Greenburg and Richard Dean Anderson, who had starred in MacGyver.
