Johnny Allegro is a black and white 1949 American film noir, starring George Raft, Nina Foch, Will Geer, and George Macready. An ex-gangster (Raft) working as a federal agent runs afoul of a crime lord (Macready) who enjoys hunting humans for sport. The picture was directed by Ted Tetzlaff and produced by Columbia Pictures. Using only the above description and what you know about the world, "Films during this time period were based on true stories when it came to gangster films" is definitely correct, incorrect, or inconclusive?
