Great Guy  Great Guy is a 1936 American crime film noir directed by John G. Blystone and starring James Cagney. In the film, an honest inspector for the New York Department of Weights and Measures takes on corrupt merchants and politicians. After the Chief Deputy of the Department of Weights and Measures is nearly killed in a car accident engineered by corrupt politician Marty Cavanaugh, he enlists ex-boxer Johnny Cave (Cagney) to take over his position. As the new leader, Johnny reiterates to his team the importance of their department and warns them that corruption is an ongoing hazard. Johnny then goes out into the field with his naive partner, Patrick James "Aloysius" Haley, investigating merchants who are accused of using faulty measures and cheating the public. He ends up fining a market for adding lead weights to stewing chickens and fining a gas station for routinely shortchanging its customers. In each case, the merchants try to bribe Johnny in exchange for ignoring their corrupt practices, but he adamantly refuses. Meanwhile, Johnny's fiancee, Janet Henry, criticizes him for being constantly hardheaded in his indefatigable pursuit of fighting corruption. Later on, Cavanaugh offers Johnny a cushy job with his organization in exchange for turning a blind eye to his citywide racket. After he refuses, Johnny is framed for both drunk driving and a robbery, but is then "exonerated" by an ornery Cavanaugh, implying that he can make or break him. Afterwards, the mayor, a puppet for Cavanaugh, offers Johnny a high paying job, but once again he refuses. When Johnny learns that Janet's boss, Abel Canning, has been swindling a local orphanage by sending them half-shipments of food but charging them full-price, he declares that he's going to expose him for the criminal that he is. Once he realizes that Canning is in an alliance with both the mayor and Cavanaugh, Johnny releases the orphanage story to the newspapers, which angers his fiancee and eventually leads to her breaking their engagement. As Johnny prepares for the case against Canning, Cavanaugh hires a thug, ex-wrestler Joe Burton, to attack and steal the evidence from him. However, instead of turning over the evidence to Canning, Burton decides to blackmail him for $5,000. While at a big cocktail party, Canning gives Burton a $5,000 check in exchange for a key to his apartment where the evidence is hid.
