Leon: The Professional is Luc Besson's greatest piece of work, an almost perfect movie. A fantastic cast brings its best to an action packed thriller about a young girl Mathlida (played by a 13 year old Natlie Portman) who befriends a hitman (Jean Reno) after her family has been massacred by a corrupt DEA agents headed up by Stansfield (Gary Oldman) who brings an intense performance to a psychotic character. - Staff Review by Christopher
