Stargate SG-1: Window of Opportunity

"Window of Opportunity" is the sixth episode from season 4 of the science fiction television series Stargate SG-1, and first aired on the American subscription channel Showtime on August 4, 2000. The episode is based on a time loop scenario, with SG-1 team members Colonel O'Neill and Teal'c repeatedly reliving the same ten hours after a mission on a planet. Since the rest of their team and all personnel at Stargate Command are unaware of the happenings and do not remember the time resets, O'Neill and Teal'c are forced to find a solution on their own. Penned by Joseph Mallozzi and Paul Mullie, "Window of Opportunity" was the writing duo's second script, and their first episode to air. Mallozzi and Mullie later became executive producers of both Stargate SG-1 and Stargate Atlantis. The episode's unique story style caused an unexpected shortage of footage during filming, which director Peter DeLuise compensated for by shooting additional scenes, many of which were humorous. "Window of Opportunity" is widely regarded as a fan favorite.
