When talking about part 3, Martin Gero called it the "biggest episode" they had done. When developing part three of "The Siege", Brad Wright and Gero handed over a copy of the script to director Martin Wood. As Wood has commented, his job was to make it "come to life in a way" that was more "exciting" than previous part. He called the episodes, a "Roller-coaster ride" because of the "Loops" and "Twists". In the last scene, where John Sheppard is stalking Aiden Ford, the portraying actors Joe Flanigan and Francks complained about their characters getting "Off a little easy." They eventually came to a compromise with the producers, since the last scene was "Really" important to the story arc of "Runner".
