The first Zorro film to feature sound and the first to be shot in color.
This is the only film to accurately depict Zorro as wearing a mask which covers his entire face, as he appeared on the cover of the August 9th, 1919 issue of All-Story Weekly; the magazine which first introduced him in the five part story The Curse of Capistrano. All subsequent film and television depictions which leave Zorro's chin, and usually his entire mouth, exposed are variations of the design first created for Douglas Fairbanks in the film The Mark of Zorro (1920)
This was Republic's first color feature although it would only utilize black-and-white prints for subsequent releases.
Prologue: "Spain's conquest of California was a saga written in blood. In a remote province the tortured Indians, text into slavery, prayed for a deliverer. As though in answer to their prayers arose Zorro--a masked, incredibly daring hero--led them in a desperate revolt which promised freedom. Then Zorro made a memorable mistake. He got caught."
