Vice President Robert Kinsey, Anubis, and Walter Harriman respectively. The shows long-time military consultant & advisor Ron Blecker made his first onscreen appearance as a member of the SG-3. Sci-fi Channel ran a "Get in the Gate" competition to appear as a background extra in the episode. Out of the 56,000 entrants, Bonnie Arbuthnot from Chicago won the role, appearing in scenes with Don S. Davis, James McDaniel & William Devane. Filming Filming "Lost City" took place in August 2003. Like much of season 7, filming took place in a particularly disjointed, out-of-sequence manner in order to accommodate Richard Dean Anderson, who was only working three days a week. In order to feature Anderson as much possible in "Lost City" the production team saved up their "Rick days". The episode was the second-to-last episode to begin filming. Amanda Tapping shot her parts for "Lost City" over 16 days. At the same time, Tapping also had to begin work on the subsequent and final episode of the season, "Resurrection", which was her directorial debut. Grass fields around Maple Ridge, British Columbia were used as the backdrop to the alien world which SG-1 travel to in search of an Ancient Repository of Knowledge. The scenes involved heavy use of gasoline mortar explosions to simulate attacking spaceships. British Columbia was experiencing uncharacteristically warm weather at the time, with an increase in wildfires, so to lessen the risk, Wray Douglas' effects team sprayed over 10,000 gallons of water onto the fields, with the Maple Ridge Fire Department on location and standing-by. The White House Oval Office set was acquired from the 2003 X-Men film X2, although the set could not be damaged. This caused director Martin Wood some limitations with shooting a scene where the shows villain, Anubis, appears as a hologram to the American President in the Oval Office, before being fired upon by Secret Service agents. As they were unable to damage the room, a number of props were made to simulate gunfire, including a portrait. The scene was then further hampered when the technocrane broke prior to filming. Wood was ultimately unsatisfied with the finished scene as he felt Anubis wasn't imposing enough. A set was constructed which would double as both the lava rock Ancient Outpost on a distant planet that SG-1 travels to and the ice covered Ancient Outpost on Earth.
