The Great K&A Train Robbery - 1926
Filmed in the Royal Gorge of Colorado.
In July 1926 Tom Mix arrived by train in Glenwood Springs, CO, for the shooting. He was accompanied by his family, 55 cast and crew members and 22 horses, including Tony the Horse, who was just as popular as his human counterpart. Two Pullman cars and two special baggage cars conveyed Mix's company and equipment.
Each day for three weeks spectators lined the Glenwood Canyon (CO) road to watch Tom Mix, Tony the Horse and the rest of the troupe complete the exterior shots. Mix performed all his own stunts, including rappelling down the walls of Glenwood Canyon. Mix and his horse also galloped the length of Shoshone Dam in one of the movie's chase scenes.
The props department for this film had a young John Wayne as one of its employees. This is one of Wayne's earliest roles, and came at a time when he was only receiving uncredited, minor parts in films.
