Sid and Nancy is my 2nd favorite.
THE PROFESSIONAL, Hands Down #1
Gary Oldman, with Jean Reno, Natalie Portman and Danny Aiello star in a go-for-broke thriller about a professional assassin whose work becomes dangerously personal. Calling himself a "cleaner", the mysterious Leon (Reno) is New York's top hitman. When his next-door neighbors are murdered, Leon becomes the unwilling guardian of the family's sole survivor - 12-year-old Mathilda, but Mathilda doesn't just want protection; she wants revenge. Training her in the deadly tricks of his trade, Leon helps her track the psychotic agent (Oldman) who murdered her family.
