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).
