G Men, one of the top-grossing films of 1935 was a shot at portraying crime successfully within the confines of the newly enforced Hayes Code, by creatively casting crime favourite James Cagney in a non-criminal role -- in this case supporting the law and maintaining the action by becoming a federal agent.
The supporting cast features Robert Armstrong and Barton MacLane and the surrounding tension arises from the fact that Cagney's character, Brick Davis changes sides and bides farewell to the mob boss who financed his education as a lawyer, to become a full on nark, a fed or what passed for it in the long-past and unarmed days of 1935.
