August Schellenberg previously played Sitting Bull in Witness to Yesterday (1973) and would later do so again in Bury My Heart at Wounded Knee (2007).
For a dream sequence, cinematographer Thomas Burstyn came up with the idea of having two cameras - one loaded with color film, the other with infrared black & white - shoot the exact same image, and then combining them in post-production. Rental house Clairmont Camera designed and built a rig that positioned one camera above the other and used mirrors to correctly align their respective images. This became known as the "Crazy Horse" or "Over/Under" rig, and was made available for rental to other productions. Keslow Camera, which purchased Clairmont in 2017, ceased offering it in 2022.
