Award-winning author and short-story writer who scripted a number of effective propaganda films (both documentaries and features) during WWII. Maltz's career was curtailed by the activities of HUAC (he was jailed in 1950 as one of the Hollywood Ten), though he wrote several American films under pseudonyms while living in Mexico from 1952 to 1962. He worked uncredited on "The Robe" (1953).
