Pickpocket is a 1959 French film directed by Robert Bresson. It stars the young Uruguayan Martin LaSalle, who was a nonprofessional actor at the time, in the title role, with Marika Green as the ingnue. It was the first film for which Bresson wrote an original screenplay rather than adapting it from an existing text.
Visiting his mother, Michel meets Jeanne Marika Green who begs him to visit his mother more often. His friend Jacques goes on a date with Jeanne and invites Michel along. But after stealing a watch, Michel leaves Jacques and Jeanne at the carnival. While in a bar, the inspector asks Michel to show him a book by George Barrington about pickpocketing at the station on a convenient morning, and Michel goes down to the police station at the appointed date with it. Once there, the inspector barely glances at the book. Michel returns to his apartment realizing that it was all just a ruse to search his apartment. However, the cops failed to find his stash of money.Michels mother dies, and he goes to the funeral with Jeanne. Later, the inspector visits Michel in his apartment, and tells him that his mother had had some money stolen, but later dropped the charges, probably knowing the thief was her son. The inspector leaves without arresting Michel, who decides to leave the country. He travels from Milan to Rome and ends up in England where he spent two years in London pulling off good jobs, but throws his earnings away on alcohol and women. ........
