Zorro Rides Again (1937) is a 12-chapter Republic Pictures film serial. It was the eighth of the sixty-six Republic serials, the third with a western theme (a third of Republic’s serials were westerns) and the last produced in 1937. The serial was directed by William Witney & John English in their first collaboration. The serial starred John Carroll who also sang the title song as a modern descendant of the original Zorro with Carroll stunt doubled by Yakima Canutt. The plot is a fairly standard western storyline about a villain attempting to illicitly take valuable land (in this case a new railroad). The setting is a hybrid of modern (1930s) and western elements that was used occasionally in B-Westerns (such as the western feature films also produced by Republic).

It was also the first in a series of five Zorro serials: Zorro’s Fighting Legion (1939), Zorro’s Black Whip (1944), Son of Zorro (1947) and Ghost of Zorro (1949).
