Léon: The Professional (), titled Leon in the United Kingdom (and originally titled The Professional in the United States), is a 1994 English-language French action-thriller film written and directed by Luc Besson. It stars Jean Reno and Gary Oldman, and features the film debut of Natalie Portman. The plot centers on Léon (Reno), a professional hitman who reluctantly takes in twelve-year-old Mathilda Lando (Portman) after her family is murdered by corrupt Drug Enforcement Administration agent Norman Stansfield (Oldman). Léon and Mathilda form an unusual relationship, as she becomes his protégée and learns the hitman's trade. Plot Léon is an Italian hitman (or "cleaner", as he refers to himself) in the Little Italy neighborhood of New York City working for a mafioso named "Old Tony". One day, Léon meets Mathilda Lando, a lonely twelve-year-old who lives with her dysfunctional family in an apartment down the hall from Léon, and has stopped attending class at her school for troubled girls. Mathilda's abusive father attracts the ire of corrupt DEA agents, who have been paying him to stash cocaine in his apartment. After they discover that he has been stealing the cocaine, DEA agents storm the building, led by their boss, the sharply dressed drug-addict Norman Stansfield. During the raid, Stansfield murders Mathilda's family while she is out shopping for groceries. When she returns, Mathilda realizes what has happened just in time to continue down the hall to Léon's apartment; he hesitantly gives her shelter. Mathilda quickly discovers that Léon is a hitman. She begs him to take care of her and to teach her his skills, as she wants to avenge the murder of her four-year-old brother. At first, Léon is unsettled by her presence and considers murdering her in her sleep but he eventually trains Mathilda and shows her how to use various weapons. In exchange, she runs his errands, cleans his apartment and teaches him how to read. Mathilda looks up to Léon and quickly develops a crush on him, often telling him she loves him but he does not reciprocate. When Léon is out on a job, Mathilda fills a bag with guns from Léon's collection and sets out to kill Stansfield. She bluffs her way into the DEA office by posing as a delivery girl, and is ambushed by Stansfield in a bathroom. One of his men arrives and informs him that Léon killed Malky, one of the
