Although this serial carries the credit "based on characters created by Johnston McCulley", none of the Zorro characters appears in this film. It was released as a Zorro film apparently so that the studio could be sure the moviegoers would come to watch the serial. Also, George J. Lewis, who plays the male hero, had usually played villainous roles to the moment. He will later play the role of Zorro/Diego's father, Don Alejandro de la Vega in the defining TV show Zorro (1957).
The fact that Randolph Meredith has no bullet wounds on him when he returns to his sister's house to die is no mistake. Serials were heavily regulated in those days--filmmakers were not even allowed to use blood packs, which would have made the shooting scenes more realistic.
