Léon (also known as The Professional and Léon: The Professional) is a 1994 French/American action thriller film written and directed by Luc Besson.
It stars Jean Reno as a mob hitman (killer), Gary Oldman as a corrupt DEA agent, a young Natalie Portman, in her feature film debut, as a 12-year-old girl who is taken in by the hitman after her family is murdered, and Danny Aiello as the mobster who gives the hitman his assignments.
The film received generally favorable reviews from critics. As of January 2011, the film holds a "Certified Fresh" rating on Rotten Tomatoes, with an aggregate rating of 78% based on 40 critical reviews. However, the inclusion of the 12-year-old Mathilda character, and Gary Oldman's deliberately overstated portrayal of corrupt DEA officer Norman Stansfield, polarized critics.
