Access to the interior of Montezuma's Castle has not been allowed to the public since 1951 for safety reasons and to protect the structures. At the end of the movie, cast members are seen climbing ladders up into the structure and some camera placement indicates that they were inside some of the rooms.
Flaming Feather (1952) was shot on location around Oak Creek Canyon near Sedona, Arizona, and at the Montezuma Castle National Monument near Sedona, an 800-year-old Indian cliff dwelling. The local Yavapai Indians, who were employed as extras on the production, refused to enter the cliff dwellings because they represented the "dwelling place of the dead." Consequently, production was delayed while a band of Navajos was brought in from a reservation 137 miles away to replace them.
Forrest Tucker's character is an army lieutenant, and his sergeant is named O'Rourke. In the TV series F Troop (1965) Tucker played a sergeant named O'Rourke.
