As a dramatist for the leftist Theatre Union, he wrote several plays, alone or in collaboration, which were presented on the New York stage in the early 30s. He also wrote novels and short stories. In 1941 he settled in Hollywood as a screenwriter. He collaborated on a number of features for Paramount and Warners, including such patriotic WW II films as DESTINATION TOKYO (1944) and PRIDE OF THE MARINES (1945). He also scripted several documentaries, including Academy Award-winner MOSCOW STRIKES BACK (1942), an American adaptation of the Soviet war propaganda film, THE DEFEAT OF THE GERMAN ARMIES NEAR MOSCOW, and THE HOUSE I LIVE IN, a documentary on tolerance that won a special Oscar in 1945. In October of 1947, Maltz was one of the Hollywood Ten who were convicted on charges of contempt of Congress for refusing to testify on their affiliation with the Communist Party. He was imprisoned for 10 months and blacklisted by the industry after his release from jail. THE NAKED CITY (1948), Jules Dasin's realistic police drama, was the last film on which Maltz received screen credit until 1970. He lived in Mexico from 1952 to 1962, occasionally collaborating on Hollywood screenplays under pseudonyms. The best known of his several novels was The Cross and the Arrow (1944), about the German anti-Nazi resistance movement. Just before his death at 76 of complications from shingles, he defied the effects of a stroke by feverishly completing his last novel, Bel Canto, about the French resistance movement.  Nominated for Writing (Screenplay) 1945: PRIDE OF THE MARINES  Special Award 1945: For the short subject on tolerance THE HOUSE I LIVE IN.
