for the use of anamorphic format aspect ratio, believing that it allowed for placing several actors in an environment, and making use of the scenic vistas available, while still creating a sense of confinement within the image. It also enabled the use of negative space around the actors to imply something may be lurking just offscreen. Principal photography began on August 24, 1981, in Juneau, Alaska. Filming lasted about twelve weeks. Carpenter insisted on two weeks of rehearsals before filming as he wanted to see how scenes would play out. This was unusual at the time because of the expense involved. Filming then moved to the Universal lot, where the outside heat was over . The internal sets were climate-controlled to to facilitate their work. The team considered building the sets inside an existing refrigerated structure but were unable to find one large enough. Instead, they collected as many portable air conditioners as they could, closed off the stage, and used humidifiers and misters to add moisture to the air. After watching a roughly assembled cut of filming to date, Carpenter was unhappy that the film seemed to feature too many scenes of men standing around talking. He rewrote some already completed scenes to take place outdoors to be shot on location when principal photography moved to Stewart, British Columbia. Carpenter was determined to use authentic locations instead of studio sets, and his successes on Halloween and The Fog (1980) gave him the credibility to take on the much bigger-budget production of The Thing. A film scout located an area just outside Stewart, along the Canadian coast, which offered the project both ease of access and scenic value during the day. On December 2, 1981, roughly 100 American and Canadian crew members moved to the area to begin filming. During the journey there, the crew bus slid in the snow toward the unprotected edge of the road, nearly sending it down a embankment. Some of the crew stayed in the small mining town during filming, while others lived on residential barges on the Portland Canal. They would make the drive up a small, winding road to the filming location in Alaska where the exterior outpost sets were built. The sets had been built in Alaska during the summer, atop a rocky area overlooking a glacier, in preparation for snow to fall and cover them. They were used for both interior
