“Open Range” was filmed entirely in Alberta, Canada, even though the story is set in Montana.

Main filming locations

  • Stoney Indian Reservation , Alberta – This was the primary location, where Kevin Costner had an entire town set for Harmonville built from scratch to get an authentic Western look.
  • Longview, Alberta – Used for key town exteriors and streets, contributing much of the small‑town Western atmosphere.
  • Calgary, Alberta – Surrounding areas and landscapes appear in travel and cattle‑drive scenes.
  • Morley, Alberta – Used for ranch and countryside scenes, with views of the Rocky Mountains and rolling hills.
