The film's principal photography was scheduled to last four months. It began on August 6, 2013, in the province of Alberta, Canada. Towns in Alberta where shooting took place included Nanton, Longview, Lethbridge, Fort Macleod, and Okotoks. In Okotoks, filming took place at the Seaman Stadium and the Olde Town Plaza. For a cornfield scene, production designer Nathan Crowley planted 500 acres (200 ha) of corn that would be destroyed in an apocalyptic dust storm scene, intended to be similar to storms experienced during the Dust Bowl in 1930s America. Additional scenes involving the dust storm and McConaughey's character were also shot in Fort Macleod, where the giant dust clouds were created on location using large fans to blow cellulose-based synthetic dust through the air. Filming in the province lasted until September 9, 2013, and involved hundreds of extras in addition to 130 crew members, most of whom were local.
