Continuity mistake: When we first see John in the shooting range, the other cop brings him news of Jack. John asks if he is in the hospital or morgue. The other guy says "worse". The shot from behind John shows he is looking right at the other guy. But then the shot changes to the other perspective and suddenly John is looking down a little and in a different direction. (00:05:45)
Continuity mistake: When we first see John, he is in the police shooting range. He has on protective head phones which he takes off and sets on the table in front of him as the other cop comes in. He and this cop talk about Jack, and when they finish, they shake hands. The mid range shot of them shaking hands shows the head phones still on the table. It then cuts to a far shot and now the head phones are gone while the two finish the hand shake. Careful which table you are looking at, as the angle makes it confusing. The head phones were on the table with the red thing on its left side. (00:06:50)
Continuity mistake: As Lucy tells John that it's not his fault, the angle showing her shows John with his mouth open. It cuts to another angle and close up of John and suddenly his mouth is closed. (00:07:10)
Continuity mistake: In the taxi, the driver says the line "I sing all the time". As he is saying this, there is a shot change. The shot from in front shows his right hand is barely visible next to the steering wheel and semi low. But the shot from behind shows his hand higher with thumb sticking up above the steering wheel. (00:11:40)
Continuity mistake: When John gets out of the taxi, the window is open. When he closes the door, the window is shut. (00:12:00)
Continuity mistake: The taxi driver looks back at John and says he doesn't have to pay because he let him sing. The shot from in front shows the steering wheel is clear. But the shot changes to behind John and suddenly the driver's arm is on top of the steering wheel and across it. (00:12:00)
Continuity mistake: When Jack and Yuri escape from the courthouse, both have their hands cuffed. After getting in the blue van for the first time, they still have the cuffs on each hand, but they are no longer chained together. (00:19:00)
Visible crew/equipment: After John stops the blue van and tries to confront Jack, Yuri takes it upon himself to get out. As he opens the door of the van, a camera and some crew equipment is reflected in the door's window for a brief moment. (00:19:05)
Continuity mistake: In the car chase near the start, the blue and white cars hit bumper to door. When the tank type car hits them they are end to end. (00:22:00)
Continuity mistake: Just after John says "Jack! I'm not done talking to ya!" It shows the blue van backing up and turning around. The first shot shows its headlights turned on, but the next shot they are off. It happens again later when the van is spun and pinned to the front of the armoured truck. (00:22:20 - 00:27:20)
Continuity mistake: The mobile tank rips a door nearly completely off a blue van. When John hits it, there is less damage to the door. (00:22:50)
Continuity mistake: In the car chase, the blue van is hit and the left side headlight dislodges and is dangling down for most of the chase. But in one far shot where the van is taking a turn, it is suddenly switched to the right headlight that's dangling. (00:23:00)
Visible crew/equipment: When the truck spins the small blue car into the crash barrier, the camera turns to look back at the car. When it does, the camera operator and the bike it's on is in shot. (00:23:10)
Revealing mistake: When the armored truck flies through the air and smashes into a concrete pipe that is being hauled by a yellow truck, there is a shot from in front of the yellow truck. You can see there is no driver. (00:28:55)
Revealing mistake: When Yuri Komarov is on the phone with his daughter, the screen on the phone is the dial screen rather than the on-going call screen. (00:34:10)
Other mistake: Komerov gets shot in the arm at the start of film, however, he is able to use his arm perfectly even straight after being shot. (00:34:30)
Continuity mistake: When John and Yuri are standing in front of the crane and talking about their children, John's arms go from crossed to by his side, back to crossed a couple times between shots. (00:39:35)
Continuity mistake: When the bad guy is eating the carrot in the big room, the amount of carrot eaten changes between shots. (00:46:20)
Audio problem: In the scene in the banquet hall, where the bad-guy is eating a carrot, he throws it on the floor. Subsequently, while chewing on the little bits he has left in his mouth, there comes a sound which is not a chewing-small-pieces-of-carrot sound, but a biting-a-piece-off-a-carrot sound. That sound was way too loud to have been produced by some little piece he had left in his mouth. (00:47:45)
Chosen answer: No. Bruce Willis (and thus, John McClane) is left handed. But guns are mostly designed for right handed people, so when he isn't holding a gun modified for him, it's easier to use it with his right hand.
