Espíritu de conquista

A good part of this movie was shot on location in southern Utah. When Fritz Lang arrived and saw the local Indians who were hired for the movie they were short stocky built people like many of the tribes in the southwestern area of the United States. This did not meet Langs idyllic picture of the tall thin and muscular Indian he had cultivated while he was still in Europe where he was already fascinated with the American west and its's western films. He promptly fired all of the local tribes people and had extras sent from central casting in Hollywood, most of whom were Anglo, to meet his view of Native Americans.
