The film is a somewhat rough mixture of correct historical fact and outright movie fiction, though it is presented in docu-drama style. It is largely accurate in the historical coverage of the event, but creates several character names that exist only in the film, rather than reality, such as "Boris Chapman" and "Adolph Muller", which the film identifies as the two phony "policemen" involved in the massacre. There is considerable speculation on who those two men actually were, but their true identities still remain unknown. It also includes some facts that are erroneously used (such as the real name of Jack McGurn's being given as "Vincenzo Demaury", an alias he used only in later years when working as a golf pro - his birth name was Vincenzo Gebaldi). The film also portrays Capone taking personal revenge on turncoat Unione Siciliano member Joe Aiello by personally murdering him. Capone did order the murder of Aiello, though it was carried out by members of his gang at a much later date. Its portrayal in the movie as having occurred before the massacre is important to the context of the film, but not the actual fact. In fairness, however, a great deal of research has been done on the Massacre in the last forty years, revealing new facts, and exploding some old theories, none of which writer Browne could have known at the time, chief among them would be the existence of the wall of the garage the mass murder happened inside a Canadian night club, the investigations of some of the suspects, and former gangsters later revealing some knowledge of the mass murder. Besides the climactic garage scene, Corman also staged a re-creation of the Moran Gang's attack on Capone headquarters in Cicero, Illinois which left Capone badly shaken, though unhurt. He also staged a stereotypical gangland funeral complete with tuxedo clad gunsels and enormous banks of flowers. Hymie Weiss is shown flying into a rage at Dean O'Banion's sendoff when the largest floral arrangement of them all reads, "From Al". Weiss himself is later killed in an ambush by the Capone mob, leaving Bugs Moran as head of the North Siders. Both Moran and Capone are repeatedly shown swearing bitter oaths of vengeance and disdain towards each other as they urge their respective underlings to wipe out "that no good louse".Each character is given a verbal voiceover biography as they are introduced, and in some video releases, the biographies of Rheinhard Schwimmer and Adam Heyer, two of the massacre victims, are removed from the soundtrack, possibly due to protest from surviving family members.
