G Men is a 1935 Warner Brothers movie starring James Cagney and Ann Dvorak that is based on the mythologized origins of the Federal Bureau of Investigation (FBI). The film's significance is less in its cinematic merits than as a propaganda effort in the FBI's so-called war on crime in the middle years of the depression. According to Variety Magazine, it was one of the top-grossing films of 1935.

G Men was made as part of a deliberate attempt to counteract what many conservative political and business leaders claimed was a disturbing trend of glorifying criminals in the early 1930s gangster film genre. Although the gangster films were typically presented as moral indictments of organized crime where the criminal protagonist inevitably died, they nevertheless depicted a life of freedom, power and luxury enjoyed by gangsters in the midst of a real-life economic crisis. Foremost of these films were Little Caesar, the original Scarface, and perhaps the most memorable, The Public Enemy, which catapulted Cagney to stardom. Also notable about these films was that law enforcement was typically portrayed as either impotent in the face of crime, or, as with Public Enemy, akin to a derelict and largely absentee father shirking his duty. Based on this interpretation, G Men supplanted the criminal protagonist with the heroic federal police officer.

It's the early days of the F.B.I. - federal agents working for the Department of Justice. Though they've got limited powers - they don't carry weapons and have to get local police approval for arrests - that doesn't stop fresh Law School grad Eddie Buchanan from joining up, and he encourages his former roommate James "Brick" Davis (James Cagney) to do so as well. But Davis wants to be an honest lawyer, not a shyster, despite his ties to mobster boss McKay, and he's intent on doing so, until Buchanan is gunned down trying to arrest career criminal Danny Leggett. Davis soon joins the "G-Men" as they hunt down Leggett (soon-to-be Public Enemy Number One) and his cronies Collins and Durfee, who are engaged in a crime and murder spree from New York to the midwest.
