Corrected entry: When Zeus begrudgingly accompanies McClane to their first riddle site at the pay phone (where the terrorist tricks them into thinking there is a bomb in the trash can), an extra walks past them going towards the street corner. Seconds later when the camera angle switches, the same extra walks towards the camera again going the other way.
Corrected entry: The scene where the cops go into Chester A. Arther School, Lambert introduces Principal Martinez to 'Inspector Carver'. The character's name is Cobb.
Corrected entry: The Beretta 92F has never been an issue weapon with the NYPD and all officers are required to carry issue weapons, even maverick detectives.
Corrected entry: If the bomb needs the two chemicals to mix, why not just drill a hole and drain one?
Corrected entry: During the bridge scene, when Willis and Jackson jump down to the passing ship, check out the background landscape - it is marshy with NO evidence of ANY tall buildings. Since this movie was supposed to take place in NYC, there should be a building somewhere. That scene was shot in Charleston, South Carolina; they chose SC because there are two bridges right next to one another (the John P. Grace Memorial Bridge and the Silas N. Pearman Bridge). Action can occur on one bridge, while they film it from the other.
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 truck hits the water the rope breaks and cuts one of the bad guys in half. Again, if you play it at slow motion, you can see that the guy has a rope tied to his back. (It's one of those machines that are used in the movies to pull something or someone back really fast.) You see the rope for about 1 second. After that it is erased.
Corrected entry: In the scene where the green Dodge falls off of the bridge, you can use slow-motion play to see extra explosives go off causing a huge splash. This happens before the Dodge actually hits the water.
Corrected entry: Throughout the film Inspector Walter Cobb is as you would expect referred to as Walter. But in the end credits he is listed as Arthur Cobb.
Corrected entry: The German version is strange, because the English is dubbed, but the German (obviously) isn't. However, this means that when they're on the boat, and the guard shouts "nicht schießen" [don't shoot], Willis asks "was hat er gesagt?" [what did he say], and is answered "nicht schießen". Bizarre....
