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). [edit] Cast William Forrest as Martin Crane Louise Currie as Alice Hamilton Johnny Arthur as Mura Sakima, Japanese saboteur Rod Bacon as Jim Arnold Richard Clarke as Frank Jeffers Anthony Warde as 'Killer' Mace David Bacon as Bob Barton Bill Healy as Terry Morton Howard C. Hickman as Warren Hamilton [edit] Additional (uncredited) cast Tom Steele as the Masked Marvel (and two Sakima thugs, both of whom are quickly killed) Gayne Whitman as The Masked Marvel's voice
