The Masked Marvel (1943) is a 12-chapter film serial created by Republic Pictures, who produced many of the best known of the serials. It was Republic’s thirty-first serial, of the sixty-six they produced.

Plot
In The Masked Marvel, a hero dressed in a business suit and a face mask fights the Japanese saboteur Sakima and his espionage organization. The hook of the story is that, in a reversal of the common serial “Masked Mystery Villain” stock character, the audience doesn’t know who the hero is until the final reel—all the audience is told is that The Masked Marvel is one of a group of special investigators (the same plotline is used in the Republic serial The Lone Ranger).
