Zero Hour (Stargate SG-1)

"Zero Hour" is the fourth episode from Season 8 of the military science fiction television series Stargate SG-1. It was written by producer Robert C. Cooper and directed by Peter Woeste. Clips of the episode were shown on Late Night with Conan O'Brien before Season 8 began, with Late Night graphic designer Pierre Bernard making a cameo appearance in the episode. The first airing of "Zero Hour" on July 30, 2004 on the American Sci Fi Channel was viewed by 3 million people. The episode received mixed reviews.

"Zero Hour" takes place shortly after the promotion of main character Jack O'Neill from Colonel to Brigadier General. With O'Neill being the new leader of Stargate Command (SGC), Lt. Col. Samantha Carter has assumed O'Neill's old position as leader of the SG-1 unit. The idea to have the episode focus on General O'Neill solving various problems at his new job came from the writers' wondering what the general of the SGC does while his teams are on missions.
