Zorro was created in 1919 by New York-based pulp writer Johnston McCulley. He debuted in "The Curse of Capistrano", serialized in five parts in the pulp magazine All-Story Weekly. At the denouement, Zorro's true identity is revealed to all. The character has been adapted for over forty films, but this serial is the most tenuous of them all!
Zorro's Black Whip is a 1944 Republic Pictures film serial starring Linda Stirling. The film was made after the popular 1940 20th Century-Fox remake of The Mark of Zorro and Republic wasn't able to use the character himself, but still wanted to capitalize on it. However, and despite the title, Zorro does not feature in this serial. The hero(ine) is actually called The Black Whip throughout.
The serial was put into production, with Linda Stirling as the main star, following the actress' popular performance in The Tiger Woman. Zorro's Black Whip was budgeted at $134,899 although the final negative cost was $145,251 (a $10,352, or 7.7%, overspend). It was the cheapest Republic serial of 1944 and was filmed between 29 July and 26 August 1944.
The surnames of the two lead characters, Meredith and Gordon, are an in-joke referencing two earlier Republic serials. The character Nyoka the Jungle Girl and her father had the surname Meredith in Jungle Girl, but their last name was Gordon in the semi-sequel Perils of Nyoka. (Source: wikipedia.org)
