James W. Horne

Serials usually spawned feature film versions, but with this film, it was the other way around. A 1932 Buck Jones Western, White Eagle was made into a serial nine years later, again starring Jones in the title role, a (supposedly) Native American Pony Express Rider defending his people against a gang of evil Whites.

The heirs of Anton Benson are searching Bensonhurst for hidden gold; they are joined by a reporter, a gangster...and a masked fiend known as The Iron Claw.

The Shadow battles a villain known as The Black Tiger, who has the power to make himself invisible and is trying to take over the world with his death ray.

Columbia's 11th serial and the first western serial that James W. Horne solo-directed.
