The western film “The Comancheros” (1961) — which is almost certainly what “the comanche ros” refers to — was filmed primarily in Utah, with some additional locations in Arizona.

Here are the key filming areas:

  • Moab, Utah region – Much of the movie was shot along the Colorado River just north of Moab, giving it those dramatic red-rock canyon vistas.
  • Dead Horse Point State Park, Utah – One of the main scenic backdrops used in the film.
  • Professor Valley, Fisher Valley, Onion Creek, Hurrah Pass, La Sal Mountains, King’s Bottom, Haver Ranch (all in Utah) – Various sequences were filmed around these classic canyon-country spots.
  • Castle Valley and Fisher Towers, near Moab, Utah – Distinctive rock formations and mesas that appear repeatedly in the movie.
  • Mexican Water, Arizona – Some additional location work was done here.

Although the story is set in Texas in 1843, the on-screen landscapes you see are overwhelmingly those Utah red-rock locations north of Moab, plus a bit of Arizona desert.
