Factual error: When the collected bad guys are at the "North of the Border" truck stop, a subtitled henchman tells Jeremy Irons that the helicopter will be ready in ten minutes. But the confused fellow actually says, "...in zwanzig minuten," which means TWENTY minutes!

Continuity: When Bruce Willis swerves into Central Park, he pulls the steering wheel hard left, but the next shot shows the car turning right.

Factual error: In the scene when Zeus goes to Yankee Stadium, the terrorists tell him to report to the home-team dugout. Yet when Zeus goes to Yankee Stadium, he is shown at the dugout along the third-base line, which any Yankee fan knows is the visitor's dugout. Given he knew which dugout he was meant to go to, and the importance of the situation, this can't just be a character mistake.

Visible crew/equipment: There is a shot towards the end of the film, (just before Willis and Jackson exchange dialogue in the engine room) in which it shows the entourage of people boarding a smaller boat from the much larger ship. Look towards the bottom left corner of the screen as the boat pulls away - inside you can see the head of a female boom mike operator.

Deliberate "mistake": While most of the German spoken in the movie is correct (even if with bad accent) there is a translation error in the scene at Yankee Stadium. When the guy with the sniper rifle gets nervous and asks if he should shoot or not, the other one says,"Nein, wir brauchen den anderen", which would translate, "No, we need the other one", but the subtitles say,"We'll follow him", which they do.

Revealing: When Willis is driving through the park, you can see the tyre marks and lines where they had driven there on other takes.

Other: 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.

Continuity: In the North of the Border scene when McClane shoots at the wires to the North of the Border neon sign, one of the two wires falls and takes out the chopper. McClane then walks back to his downed chopper, looks back at the North of the Border sign, and you see two wires going to the sign.

Factual error: In the scene where Bruce Willis and Samuel L. Jackson are in the minivan with the feds, the bad guy rings up. This call is taken on an old Motorola flip phone. They plug it into something to make it hands free loud speaker. The thing they plug it into is actually the house charger that comes with the phone, it doesn't have a loud speaker and it's also mains voltage. You can even see the spare battery in the second slot at the back of the charger and the red LED flashing to indicate that the battery is charging.

Factual error: In the North of the Border scene when McClane's helicopter makes an emergency landing you can see a Giant Food trailer in the background. They are supposed to be in Canada, but this grocery store chain is located in the Mid-Atlantic states. This scene was actually filmed in Jessup, MD where Giant has its headquarters.

Factual error: In the bridge scene where Willis & 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 NY city, there should be a building somewhere. That scene was shot in Charleston, South Carolina; they chose SC because there are 2 suspension bridges right next to one another. Action can occur on one bridge, while they film it from the other bridge.
