Crackers is a 1984 American film directed by Louis Malle. It was entered into the 34th Berlin International Film Festival. Written by Jeffrey Fiskin, the film is about a group of small-time out-of-luck thieves, led by the unemployed Weslake, who attempt to rob the neighborhood pawn shop owned by the greedy Garvey. It's a remake of the Italian film Big Deal on Madonna Street directed by Mario Monicelli.
