Léon: The Professional, also known simply as Léon, is a 1994 action thriller film written and directed by Luc Besson. The film stars Jean Reno as Léon, a professional hitman, and Natalie Portman as Mathilda, a young girl whose family is killed by a corrupt DEA agent (Gary Oldman). Mathilda seeks out Léon's help to get revenge and Léon reluctantly agrees to teach her the ways of the assassin.
Léon: The Professional received positive reviews for its stylish action sequences and the strong performances by Reno and Portman. It has become a cult classic and is considered one of Besson's best films. The film is known for its controversial themes and scenes involving Mathilda, who is only 12 years old in the film, and the relationship between her and Léon, which some critics have described as inappropriate. However, others have praised the film's handling of the relationship and the way it subverts typical gender roles. Overall, Léon: The Professional is a stylish and action-packed film with strong performances, but may not be suitable for all audiences due to its mature themes and content.
