Corrected entry: 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.
Corrected entry: In the scene when Simon asks Inspector Cobb to have McClane come to Harlem on the phone, he just mentions the address/location and the Inspector hangs up the phone. There are no further instructions given, as to what McClane has to "do" at Harlem (which McClane does in the subsequent scenes).
Corrected entry: 'Simon' needs McClane alive until the very end, when he has secured the gold. Diverting the police by making them think he is merely avenging his dead brother is a vital part of his plan. It therefore makes no sense at all that his very first task for McClane - wearing a grotesquely racist sandwich board as he walks through Harlem - could very easily get him killed.
Corrected entry: The bomb on the train has to blow up, and Bruce Willis is not supposed to find it. But he does and throws it out the back of the train just before it blows up. But the bad guy didn't expect this, he expected in to blow up in the train. In which case hundreds of people would have been killed, injured and trapped. It would take the rest of the day to clear that mess - making it impossible for them to raid the bank. Pretty crap plan - I guess he got lucky?
Corrected entry: When the No. 3 train is arriving at Wall Street, we see that that the head car is slowing, about to stop at the end of the platform. However, when McClane shatters the storm door window at the rear of the train to eject the bomb, we see the train is still moving at speed through a local station. This is because the train interior footage with McClane was shot on the actual subway here in New York, while the exterior shots were filmed on the set in Mount Pleasant, SC.
Corrected entry: The explosive the bad guys have chosen is not easily 'booby-trapped'. The two chemicals have to be mixed to produce an explosive. The fact that no one, including McClane, (who knows this) thinks to just clip one of the hoses and prevent the chemicals from mixing seems a little far-fetched.
Corrected entry: In the park, McClane and Zeus are challenged to fill one 5-gallon jug with only 4 gallons of water, using it and a 3-gallon jug. When they solve the problem, they put the 5-gallon jug with, supposedly, 4 gallons of water in it on the scale to deactivate the bomb; however, the 5-gallon jug, on the scale, is filled only halfway, no where close to where the 4-gallon mark should be.
Corrected entry: When the two officers go to rescue the kids that are stuck in the classroom they for some reason try and escape by going to the roof. However you see that there is a good solid two minutes and fifteen seconds left before the so called bomb is going to go off. Why wouldn't they just go out the front doors?
Corrected entry: After the subway explosion and the dump trucks are coming on the scene and the cop (who later gets killed) is waving them through. One of the lead terrorists is riding on the side of the truck. A few scenes earlier the same cop is in the van with McClane and the FBI agents looking at snapshots, and the same terrorist is shown, trademark square sunglasses and all. Some detective...
Corrected entry: Right after the train station explosion McClane is sitting down and talking to Zeus and Det. Lambert. McClane says "What were the odds of us making it down there on time?" which is replied by Zeus as "Zip". Zeus got to the phone at the train station on time, with time to spare. If McClane would have continued in the cab with him they would both have gotten there in time.
Corrected entry: The Germans say they are going to blow up the gold in the Long Island Sound, but they take the trucks up the aqueduct, which is on the other side of Manhattan on the Hudson River. They did not have enough time to go on the aqueduct and another bridge and end up on the Long Island Sound.
Corrected entry: In the scene where Bruce Willis kills the two bad guys in the truck in the aqueduct, he is walking towards the truck from behind left. When he shoots, he is still behind left of the truck. Then the camera changes and you see the blood spraying out of the bad guys torso. How could Bruce Willis be able to hit the torso of those guys if he was left behind the truck? It would have been okay if he had shot them from the front. That he was able to hit the guy sitting on the right side is really amazing.
Corrected entry: After Zeus and McClane escape the boat, Zeus asks Lambert to give McClane a quarter to go call his wife. However in the very last scene of the movie Zeus hands McClane a quarter to go call his wife. How on earth did he get that quarter? He obviously didn't have one the first time so why does he suddenly have a quarter now? Not like it would have mattered anyway, considering you don't need any money to make a collect call.
Corrected entry: When dealing with the binary liquid bombs you always see two equal volume containers with both containers completely full. As stated near the beginning of the movie the red liquid pumps into the clear in order to mix. If both tanks are full, how is there any volume left to pump in the other chemical in order to mix it? At least one of the tanks would need to be half full in order for there to be room to pump in the second chemical.
Corrected entry: When Ricky and the two officers are leading the terrorists down into the subway, we see two of the terrorists tranquilize the officers. The shot then cuts to Ricky, who notices the downed officers and is shot. As soon as the shot cuts to Otto and the other terrorist shouting, the two who tranquilized the guards are in full police uniform. I wish I could get dressed in five seconds...
