Oscar is a 1991 American comedy film directed by John Landis. Based on the Claude Magnier stage play, it is not a remake of the 1967 film of the same name, but bears certain similarities to the original French film.
The story is set in Depression era New York and centers around a mob boss trying to go straight. The film stars Sylvester Stallone, Marisa Tomei, Ornella Muti, Tim Curry, and Chazz Palminteri.
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.
