Continuity mistake: Throughout the limo chase scene, Tia's scratch on her face disappears and changes from cheek to cheek. (01:49:10 - 01:56:00)
Continuity mistake: In the scene when Harry brings Helen's purse to Gibbs in the van, it is raining very hard. When Harry is standing along side of the van talking to Gibbs who is in the van, he is not getting wet and there is no rain falling when the camera is facing in towards the van. However, when the camera angle is facing out away from the van, it is pouring rain and Harry is getting wet. (00:49:15)
Continuity mistake: In the scene where Harry is trying to get the truth from Gibb about Helen's phone conversation, the van pulls over and the wheels are facing to the right. They get out and talk and Harry then punches the window through. As they get back in the van and pull away, the wheels are facing the opposite direction. (00:56:55)
Continuity mistake: The scene in the SUV where Harry asks Tom Arnold 'if there is anything new', and he answers 'no', you see that they were driving straight, but when the camera does a wide shot, you would see a building directly behind them which means they would have been driving through the building.
Continuity mistake: When Harry and Gib are interrogating Harry's wife, she says a line "I don't give a s**t if you understand that or not," and the shot is a close up of her on the heat screen. Notice that her head is tilted down. However, when the shot cuts to the wider angle you can see the heat monitor and her head is instantly at a more upright angle without time for her to move.

Continuity mistake: Before Salim Abu Aziz kicks the bathroom stall doors, we can see there are 6 stalls (and Harry is in the 6th one). Salim kicks the first door, but the close up shot shows it's at least the 2nd door since we can see a door to the left of the post with the lock on it. After that he kicks the 2nd and 3rd door. After he kicks the 4th door, Harry crashes out of his stall, but he's 3 stalls over instead of 2.
Continuity mistake: During the bridge sequence, the limo drives through an area that is on fire. After emerging from the fire, the passenger side headlights are shown to be blackened from the smoke and heat. Further down the bridge the headlights are shown to be clean and new looking again. (01:56:40)
Continuity mistake: After the shootout in the restroom, close to a hundred rounds were fired, all from LOUD guns, yet when Arnold and the terrorist are running through the mall and out the window, people are standing around in the stores, like they never heard a thing. Heck, that AK-47 would even be heard by the people outside on the street. The only one to hear anything is the guy on the toilet. (00:33:30)
Continuity mistake: When Harry is racing the police horse through the park and hotel you see the end of his reins flip up several times. They are regulation length leather reins. Yet when the horse stops and flips him off over the edge of the building, suddenly the reins are about 10 feet long and much thicker. Also, in reality, the reins would probably have snapped or the bridle would have broken had 200 plus pounds hit the end of them at that speed. (00:34:45)
