Baltar is the biggest Cylon collaborator among the humans, but Roslin seemingly supports the bombings. After a Number Eight (Sharon) Cylon model was imprisoned onboard Galactica for the majority of the second season, the producers decided they needed to have her released, as they believed the storyline ran its course, and make her worthy for Adama's trust. "The swirl", a sex position Ellen Tigh uses, was a reference to Seinfeld, a comedy series Moore was a fan of. The sequence leading up to the Cylon Centurions lining up to execute the prisoners was an homage to The Great Escape, particularly the scene featuring the death of Richard Attenborough's character from the Nazis after stopping the truck he was in, and telling him to take a break, at which point he was executed. Madeline Parker was cast as Kacey Brynn. Parker's performance impressed the producers, as they believed she was "one of the better child actors" they ever worked with, since casting them, especially at a younger age, was not easy. The one problem they had with Parker however, was filming her lying injured on the stairs. In the scene where the NCP arrest civilians at night, the idea of using night vision, which did not come from the original script, came from director Sergio Mimica-Gezzan. Real night scopes were used to ensure the authenticity of the effect. One of the main visual effects of the episode was another suicide bombing which was caught on camera. Moore stated to have "tortured the visual effects guys about [it] quite a bit," because the camera footage was in black and white and the visual quality of the explosion had to be degraded to match the footage. Much like "Occupation", "Precipice" also features scenes filmed on the Colonial One set featuring several copies of the same Cylon models. Furthermore, Mimica Gezzan decided to shoot a 360 degree angle around the set, requiring additional digital duplication. The actors had to change their clothes between every take, which normally took as long as 30 minutes, after including time for touch ups on hair and makeup. The countryside of New Caprica was featured more towards the end of the episode. The producers found it a challenge to differentiate New Caprica from Caprica, the name of the planet New Caprica was named after following the holocaust from the miniseries, and featured extensively again during the first season, and
