Leon (1994)
1 factual error
Directed by: Luc Besson
Starring: Gary Oldman, Jean Reno, Natalie Portman, Danny Aiello
Continuity mistake: In the very first scene where Old Tony is debriefing Leon, we see Leon pick up his glass of milk and drink the entire glass. However, if you look at the reflection of Leon's glasses as he takes the glass away from his mouth, you can see that the milk is not finished. (00:02:30)
Trivia: Keith A. Glascoe, who plays Benny, one of Stansfield's (Gary Oldman) men, was also a New York Firefighter and sadly died carrying out his duties during the September 11 attacks on the Twin Towers.
Answer: No specific reason is given; it's most likely intended to highlight that her family are bad people (they are drug dealers after all) and to show in contrast that Mathilda and her little brother are not, so we feel badly for them.
