Burt Mustin's movie debut.
Ronald Reagan was a serious breeder of horses during this period of his career and insisted on riding his favorite mare in this film.
As the Indians were shot off of their horses, they were instructed to loop around the set, get back on different horses, and come back on as different Indians.
The producers of this movie, William H. Pine and William C. Thomas, were known in the industry as "The Dollar Bills" because they made movies so quickly and efficiently that their films seldom if ever lost money. This was their most expensive production to date, mainly because of its cast of higher-paid stars. It was also their biggest hit.
