Oscar

Angelo "Snaps" Provolone made his dying father a promise on his deathbed: he would leave the world of crime and become an honest businessman. Despite having no experience in making money in a legal fashion, Snaps sets about to keep his promise. He is faced with numerous problems: henchmen who know nothing but crime, the police who are convinced he is hatching a master plan, and Oscar, who has just got his daughter pregnant.

Oscar is a 1991 comedy film directed by John Landis. Based on Claude Magnier stage play, it's not a remake of the 1967 film of the same name. The story is set in Depression era New York and centers around a mob boss trying to go straight. The film stars Sylvester Stallone, and was a rare attempt by the actor at doing a comedy role. The film is directed as if it were a film of that time with humor and dialogue delivered in a manner reminiscent of old Hollywood comedies.
