Leon: The Professional (1994) Luc Besson Hadn't seen this for a long time ( third viewing, I think ). Jean Reno is Leon, a hitman in NYC for an Italian concern. Mathilda ( Natalie Portman ) is a waif whose parents were murdered because her dad stepped on some drugs that he had been holding for a group of corrupt cops. Mathilda escapes being gunned down and seeks asylum with Leon, who takes her in and begins to teach her the ropes. The charm of the movie resides in the quirky relationship btwn Leon and Mathilda. Gary Oldman plays a corrupt DEA agent who is about as wacked out as one can be. A French action cult classic.
