This film also goes by the name Leon. It stars Jean Reno, Gary Oldman and Natalie Portman in only her second film as a young girl. The movie takes place in New York and centers around an eccentric recuse named Leon, who happens to be a contract killer.
He and Natalie Portman's character live in the same building and through a sequence of events he becomes responsible for her. The most interesting part of the movie surrounds their relationship. They make quite a pair. Garl Oldman also delivers an exceptional performance as a deeply disturbed crooked cop.
This movie is a must see.
