Quick Answer: G Men is a 1935 Warner Bros. crime film starring James Cagney, Ann Dvorak, Margaret Lindsay and Lloyd Nolan in his film debut. According to Variety, the movie was one of the top-grossing films of 1935. The supporting cast features Robert Armstrong and Barton MacLane. G Men was made as part of a deliberate attempt by the Warners to counteract what many 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, in which Cagney portrayed street tough Tom Powers, the role that catapulted him to stardom.
