Standing Rock Indian Reservation
Though sympathetic to the Native Americans, Minnesota producer Wilfred R. Frank (1892-1960) irritated the Sioux by not filming his epic at the Standing Rock Indian Reservation. One of the first Westerns made in CinemaScope, Frank filmed in Mexico (using Mexican extras) due to cheaper costs. However, according to Cody, Estudios Churubusco overcharged Frank's production by several hundred thousand dollars.
