The Miracle Rider is a 1935 Mascot movie serial directed by B. Reeves Eason and Armand Schaefer. The serial stars silent movie cowboy star Tom Mix in his last major film role.
This was Tom Mixs last film and his only sound serial. Tom Mix was still an Alist star in 1935, alongside Charles Chaplin, Douglas Fairbanks, Sr. and Mary Pickford. He was paid 40,000 for four weeks work on The Miracle Rider, which he used as urgent funding to support his circus.The serial combined the large cast and interlocking plots of a silent serial with the science fiction and cliffhangers of the sound era. Filming of the outdoor action sequences took place primarily at the Iverson Movie Ranch in Chatsworth, Calif., on the outskirts of Los Angeles. The movie ranch, which had been in use as a filming location since the early silent movie era, was known for its rugged landscape and giant sandstone boulders. One of those boulders became known as Tom Mix Rock in later years, after it was discovered that bootholes had been carved in the rock to help the actor shoot a scene atop the rock for The Miracle Rider. ........
