Other mistake: In the scene where Nicole opens her locker and a note from David falls out, the handwriting is exactly the same as the seen where Nicole leaves a note taped to the bedroom door for her father. Although the letters are larger, the same applies to the note on the father's vandalized car, which says he's popped both of their cherries.
Other mistake: When Nicolas Cage is chasing Sean Connery in the yellow Ferrari, someone already mentioned that the windshield breaks more than once and in the next shot it's in perfect condition again, well I say forget even that. When Cage drives onto the sidewalk and crashes into the meters, the windshield should have been completely destroyed, not cracked. And the same goes for the hood of the car, which is in perfect condition in the next shot.
Other mistake: During a chase, Gibson makes a left turn at an intersection causing two girls to suddenly lunge backwards to avoid getting hit. The girl with the long black hair turns to her friend and smiles. This was most likely because she just successfully played a part in a big movie, but I don't think she'd be smiling at that moment. Most of the people in that shot don't react normally but are more explainable given the New York setting.zephalis
