The film was shot outside of Mexico City, and star Mary Murphy caught "Montezuma's Revenge" and was very ill throughout the six-week shoot. Most of her scenes are relatively brief, possibly because of this.
According to an article in "Newsweek" (4/29/53), Boris Karloff was originally intended to play Sitting Bull.
J. Carrol Naish's portrayal of Sitting Bull was adapted into cartoon form by William Hanna and Joseph Barbera as Crazy Coyote in a Huckleberry Hound cartoon.
J. Carrol Naish, who plays Sitting Bull in this film, also played Sitting Bull in "Annie, la reine du cirque (1950)".
It is odd that Iron Eyes Cody is listed as a technical director of this film since he is an italian, born Espera Oscar de Corti in Louisiana.
