Crime and Gangster Films are developed around the sinister actions of criminals or gangsters, particularly bank robbers, underworld figures, or ruthless hoodlums who operate outside the law, stealing and violently murdering their way through life.
Criminal/gangster films date back to the early days of film during the silent era. One of the first to mark the start of the gangster/crime genre was D. W. Griffith's The Musketeers of Pig Alley (1912) about organized crime. It wasn't the first gangster movie ever made, but it was the first significant gangster film that has survived. It wasn't until the sound era and the 1930s that gangster films truly became an entertaining, popular way to attract viewers to the theatres, who were interested in the lawlessness and violence on-screen. The events of the Prohibition Era (until 1933) such as bootlegging and the St. Valentine's Day Massacre of 1929, the existence of real-life gangsters (e.g., Al Capone) and the rise of contemporary organized crime and escalation of urban violence helped to encourage this genre. Many of the sensationalist plots of the early gangster films were taken from the day's newspaper headlines. The talkies era accounted for the rise of crime films, because these films couldn't come to life without sound (machine gun fire, screeching brakes, screams, chases through city streets and squealing car tires). The perfection of sound technology and mobile cameras also aided their spread. The first "100% all-talking" picture and, of course, the first sound gangster film was The Lights of New York (1928) - it enhanced the urban crime dramas of the time with crackling dialogue and exciting sound effects of squealing getaway car tires and gunshots.
Warner Bros. was considered the gangster studio par excellence, and the star- triumvirate of Warner’s gangster cycle, all actors who established and defined their careers in this genre, included: Edward G. Robinson, James Cagney and Humphrey Bogart. Others who were early gangster stars included Paul Muni and George Raft.
Three great classic gangster films (among the first of the talkies) marked the genre's popular acceptance and started the wave of gangster films in the 1930s in the sound era. The lead role in each film (a gangster/criminal or bootleg racketeer of the Prohibition Era) was glorified, but each one ultimately met his doom in the final scenes of these films, due to censors' demands that they receive moral retribution for their crimes. The first two films in the cycle were released almost simultaneously by Warner Bros.: Mervyn LeRoy's Little Caesar (1930, William Wellman's The Public Enemy (1931).
Howard Hawks' raw Scarface: The Shame of a Nation (1932), a Howard Hughes' produced film from UA starred Paul Muni as a power-mad, vicious, immature and beastly hood in Prohibition-Era Chicago (the characterization of Tony Camonte was loosely based on the brutal, murderous racketeer Al Capone).
The ultra-violent, landmark film in the depiction of Italian-American immigrant gangsters included twenty-eight deaths, and the first use of a machine gun by a gangster. Over fifty years later, Brian de Palma remade the film with Al Pacino in the title role of Scarface (1983).
The coming of the Hays Production Code in the early 1930s spelled the end to glorifying the criminal, and approval of the ruthless methods and accompanying violence of the gangster lifestyle. The censorship codes of the day in the 1930s, notably the Hays Office, forced studios to make moral pronouncements, present criminals as psychopaths, end the depiction of the gangster as a folk or 'tragic hero,' de-glorify crime, and emphasize that crime didn't pay. One way the studios quieted some of the protest and uproar over "America's shame" was to shift the emphasis from the criminal to the racket-busting federal agents, private detectives, or "good guys" on the other side of the law. In William Keighley's G-Men (1935), the best example of this new 'gangster-as-cop' sub-genre, screen tough guy James Cagney starred as a ruthless, revenge-seeking, impulsive, violent FBI agent to infiltrate criminal gangs on a crime spree in the Midwest. Although he was on the side of the law working undercover, he was just as cynical, brutal, and arrogant as he had been in his earliest gangster films.
