The Miracle Rider was the last film of Tom Mix and his horse Tony, Jr. (Tony Sr. had departed this earthly realm). It is a sound serial from Mascot with twice the normal Mascot budget. Mix was 55 when he made this and showing it. Although his voice was deep and suitable for sound, and he was still in good shape, Mix looked his age and was now using a stunt double for complicated stunts. Mix had made several sound films for Universal, but they fared only moderately well. Mix had officially retired and was promoting his Tom Mix circus when he was talked back to the silver screen for one last go round. It is fortunate he did. The Miracle Rider was an astounding success, making both Mix and Mascot over ten times its investment. The serial is one of the better serials of the period, too, and so Mix went out on top, dying five years later in an automobile accident. Even though Mix had been out of the public eye for five years following Miracle Rider, his death caused a large outpouring of grief. Mix’s enigmatic life, career and tragic demise are the stuff of legend.
