deliver their lines due to coldness—notably Christopher Judge who at times was unable to maintain the deep imposing voice of his character, Teal'c. Many of the costumes worn by extras were soaking wet and covered in mud as the day went on. Problems continued over the following days as production moved to filming the teams escape the prison on Chulak. As the scene required the seamless transition of the characters escaping out of the prison and into the surrounding alien forest, production opted not to construct the prison on a soundstage, but rather to build the set on location, in the mountains. The weather caused the set to keep blowing over, and eventually production staff were enlisted to physically hold the walls in place during shooting, to stop the set collapsing. Another issue, as noted by writer and producer Brad Wright, was that the set was so big, they didn't have enough background actors to adequately fill it. Instead, just prior to shooting they had to move the walls to make the room smaller. The Stargate Command set was to be built on Stages 5 and 6 at The Bridge Studios in Vancouver, however the buildings were still under construction and would not be complete in time for filming the pilot. As a result, production designer Richard Hudolin and construction coordinator Thom Wells designed and built the Stargate Command set in the effects stage at Bridge Studio, where it stayed for the pilot and subsequent episode "The Enemy Within", before being taken apart at the end of February 1997 and moved to its permanent home. Offscreen, over the course of filming the pilot, Amanda Tapping, Michael Shanks, and Christopher Judge, who had all relocated to Vancouver for the show, were all staying in the same hotel and would spend the vast majority of their time together after work. The three actors would go on to attribute their great on-screen chemistry to the genuine relationship and familiarity they were able to establish whilst making the pilot. Post production and effects Over 240 special effects were featured in the original cut of the pilot, with the post-production team working from when filming wrapped in March all the way through until July before the premiere. A mixture of practical and computer effects were used in the pilot. Matte paintings were used as backdrops and to extend locations, such as the Abydos Pyramid, which
