L'uomo senza paura

The horse that Kirk Douglas is riding in the film is a movie star in his own right. The horse's name is "Pie" and appears in many Western movies, mostly those with the actor Jimmy Stewart. Besides Stewart and Douglas, he was ridden by Glenn Ford and Audie Murphy. Pie appeared in 17 Westerns. Jimmy Stewart loved the horse and said he was "...one of the best co-stars I ever worked with." Pie can be seen in, amongst others, Terra lontana (1954), Winchester '73 (1950), and Là dove scende il fiume (1952). Pie lived until 1970 and was buried on Jimmy Stewart's ranch in California.

The name of the ranch is the Triangle, but the branding iron is in the shape of a circle.
