Corrected entry: It is rather obvious that Stansfield freaks out easily and is not a very reliable person. (For example when the police interrogate him about what happened to Matilda's family he behaves quite rudely.) So why can he work at the DEA? Shouldn't they choose their officers more carefully?
Corrected entry: Stan bursts into Toni's birthday bash and they chat about the 'Italian' hitman. The balloons in the restaurant are moving behind Toni, but behind Stan they are completely still.
Corrected entry: Towards the end of the movie, after Stansfield shoots Leon and Leon gives Stansfield the grenade pin, there is an elaborate explosion. The first view of the explosion is from the down the street, and you can see there is a small explosion coming from underneath a police car at the exact instant the grenades go off. There is a possibility that the car might have blown up, but that would have been after the grenades went off first and after the car had been on fire for a while. (02:02:00)
Corrected entry: When Mathilda is shown leaving the scene of the stakeout/shootout at the end, she gets on a tram to head back to school. However, the school, as stated by the headmistress on the phone, is in New Jersey. The tram Mathilda takes is a tram that goes only to and from Roosevelt Island (near Manhattan). Not only do you not get to or from New Jersey using the Roosevelt Island tram, but Mathilda would have had no occasion to be on that tram at all - she lives in either Manhattan or Brooklyn (looks more like Manhattan) and you don't use that tram to get from either of those to New Jersey either. Neither Danny Aiello's character, nor Mathilda's school, nor any of the hotels the two stayed in, nor Mathilda's home, nor anywhere else, would have been near Roosevelt Island or had her getting on that tram.
Corrected entry: There are some inconsistencies with where Mathilda is supposed to be going to school. First of all, her father knows she goes to a boarding school and, according to the headmistress, she was supposed to be there at the time of all these events. Yet he asks her if she's done her homework, and she replies "I did it already" - implying that he thinks she's supposed to be going to school somewhere near home. Second, these events are all occurring in July - it's possible that a boarding school would have year-round classes, but as far as I know New York schools do not.
Corrected entry: After Leon escapes from the SWAT team by putting on a SWAT uniform, he shortly takes off the gas mask when the medic is examining him. Stansfield then sees him and recognizes him. However he never came face to face with him before and I don't think he saw any pictures of him, so he shouldn't be able to recognize him.
