Continuity: In the scene where John and Zeus are being chased by the German guys in the car, John asks Zeus to pull out all the fuses in the fuse-box. The next shot is a quick shot of the speedometer etc. and it is lit up. Surely if all the fuses were out it wouldn't be lit?

Continuity: In the taxi scene were you see the ambulance escort pull onto the road; you see John swing around a corner going very fast, when Zeus says "slow the fuck down McClane". He gets ready to pass a large black car but the next shot (an in car shot) you can see that he never passes the car.

Continuity: When McClane is entering the subway, a man in a suit and a blond woman in a red dress pass behind him twice.

Continuity: When the police van leaves McClane semi naked on the street, his beard is a mere shade. When he mets Zeus, 10 minutes later, his beard has grown much larger.

Continuity: When Willis washes the blood off his face after shooting the bad guy in the elevator, the "towel" he wipes his face has no blood on it at all. Even after washing the worst off with the water it would still be full of blood.

Continuity: In Harlem, in the scene where Zeus gets his arm cut by the black dude wielding the switchblade, another black dude is swinging the bottle toward McClane's head-with his left arm. The following scene, McClane gets his head injured from the same bottle wielded by the same dude-only this time wielded by his right arm not his left.

Continuity: When the police get to Chester A. Arthur school and the kids are all in the auditorium, we see Detective Lambert walk into the auditorium wearing no badge in his jacket pocket. In the very next shot, he is wearing it again.

Continuity: In the car chase scene where the Germans are in the Dodge Ram and Zeus and John are in the car, during the mid point of that scene you'll notice the ram has a hood, and a few seconds later it is missing it.

Revealing: When John is fighting the huge German thug on the boat towards the end, he flips him over his shoulder and on to the steel floor, which slides apart. It is obviously rubber sheets molded and painted to look real. The shot is an overhead shot and only lasts a second.

Continuity: During the Federal Reserve scenes, the driller machine cuts a hole in the wall into one of the gold deposits. In one scene, the gold is stacked at the same level. When we see the room on the television screen, there are 2 different height levels of gold in the room.

Continuity: At the beginning, when the big explosion occurs, watch the 2 last shots. Close shot from two blocks away: Big traffic jam. Wide shot from above: Half of the cars have disappeared from the same spot.

Other: After McClane hits Targo with the chain and knocks him out, McClane searches him. Targo's body is not only in a different position, but the chain is wrapped around his head, which McClane never did.

Revealing: When Charlie (the bomb technician) hears that there are still children in the school, he continues trying to disarm the bomb. Pay attention to the shots of the countdown timer. It goes straight from 1:01 to 0:59. There is no 1:00.

Revealing: In the scene where Bruce Willis is searching the subway cars, take note of the passengers. The same people appear in the two consecutive cars. The actors just made minor changes such as adding/removing hats and glasses. The woman who screams is the most obvious.

Continuity: There is a scene where Samuel L. Jackson and Bruce Willis are in a crowded park, and they have to defuse a bomb by measuring out water. Before they do that, he picks up a cell phone and calls a bad guy with it. When he is beginning the conversation, the cell phone antenna is down. They change to a different angle, and the antenna is up.

Factual error: The security guard at the vault door fires a few shots from his handgun (about 6) down the hall towards Simon and the other terrorists. He then loads one of the shotguns and calls for help. After finding that the front guard was a terrorist he fires 14-15 rounds from the same shotgun before he is killed. The problem is that it was a Remington 870. Like most shotguns that size they only hold 8 rounds, or 9 if one is chambered.

Factual error: In the scene where Simon is standing in the cellar and all the heavy and loud machines behind him are collecting all the gold he is telling John about a riddle. John understands every word but didn't hear the noise in the background, not to mention that Simon gets a perfect signal despite being underground. I wish I had that cell phone ...

Revealing: When fighting with Targo on the boat, McClane pulls a chain, which trips Targo over. When we see Targo being tripped from above, you can see it is a stunt double - not only is he bigger than the actor playing Targo, but also his hair is grey unlike Targo's brown.

Continuity: When Samuel L Jackson runs down the stairs in the subway station, he checks the clock, which reads 10:19:10. Then when the train destroys the clock a bit later, the time's now 10:20:24, though well over 2 minutes has passed (only counting Samuel L Jackson's scenes, as Bruce Willis' presumably take place simultaneously. Counting them separately it's even longer).

Continuity: Towards the end, when Bruce Willis notices the writing on the aspirin bottle, he leaves it in the phone booth and the camera jumps towards it a couple of times. In the first shot the writing's almost vertical, but in the following shots it's at a definite angle.
