The Public Enemy (Enemies of the Public in the UK) is a 1931 American all-talking pre-Code gangster film produced and distributed by Warner Bros. The film was directed by William A. Wellman and stars James Cagney, Jean Harlow, Edward Woods, Donald Cook and Joan Blondell. The film relates the story of a young man's rise in the criminal underworld in prohibition-era urban America. The supporting players include Beryl Mercer, Murray Kinnell, and Mae Clarke. The screenplay is based on an unpublished novel—Beer and Blood by two former newspapermen, John Bright and Kubec Glasmon—who had witnessed some of Al Capone's murderous gang rivalries in Chicago. In 1998, The Public Enemy was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". Plot As youngsters in 1900s Chicago, Irish-Americans Tom Powers and his lifelong friend Matt Doyle engage in petty theft, selling stolen items to "Putty Nose". Putty Nose persuades them to join his gang on a fur warehouse robbery, assuring them he will take care of them if anything goes wrong. When Tom is startled by a stuffed bear, he shoots it, alerting the police, who kill gang member Larry Dalton. Chased by a cop, Tom and Matt gun him down. However, when they go to Putty Nose for help, they find he has left town. Tom's straitlaced older brother Mike Powers tries and fails to talk Tom into giving up crime. Tom keeps his activities secret from his doting mother. When America enters World War I in 1917, Mike enlists in the Marines. In 1920, with Prohibition about to go into effect, Paddy Ryan recruits Tom and Matt as beer "salesmen" (enforcers) in his bootlegging business. He allies himself with noted gangster Samuel "Nails" Nathan. As the bootlegging business becomes ever more lucrative, Tom and Matt flaunt their wealth. Mike finds out that his brother's money comes not from politics, as Tom claims, but from bootlegging, and declares that Tom's success is based on nothing more than "beer and blood". Tom retorts in disgust: "Your hands ain't so clean. You killed and liked it. You didn't get them medals for holding hands with them Germans." Tom and Matt acquire girlfriends, Kitty and Mamie, respectively. Tom eventually tires of Kitty; when she complains once too often, he angrily pushes half a grapefruit into her face. He then drops her
