Continuity: In the first scene with Josh Hartnett and Harrison Ford, where they are at the club's murder scene, Josh's hair is first swept over his forehead, and then, the next shot shows it's not. Then a few shots later, it is over his forehead again.

Continuity: In the scene with the car chase, the mustang gets dented and scratched many times, during the chase the scratches and dents appear and disappear. For example the front bumper is almost falling off but then in the next shot it looks brand new.

Revealing: In the scene where Harrison Ford is chasing Isaiah Washington through the building (at the beginning of the chase), Ford climbs out a window and then falls back into a multi-paned window which breaks. As he is getting up, if you look at the top pane of glass (still intact) you can see dents and such making it quite obvious that the glass was fake.

Revealing: In the sequence in which Antoine Sartain throws a flare to set fire to the car with the two dead bodies, you can see it hit the floor from the left, but the fire comes from a complete different angle.

Visible crew/equipment: In the scene of the car chase, when Josh Hartnett is driving the van with the family in it; right before they crash against the wall (in a side angle shot) you can see that the kids in the van are actually stuntmen, because they look a lot bigger than children.
