Live Free or Die Hard (2007) - 86 mistakes

Continuity: When John and Lucy are having an argument at the start of the film, Lucy's hair is over her shoulder or not over her shoulder, depending on the shot.

Continuity: John throws Matt to the floor when Matt is first being shot at. John lays on Matt to protect him and you can see that John's legs are off to Matt's left and are lying flat on the floor. The scene cuts to a view that's from behind their feet and now John's legs are no longer flat on the floor, his lower body is turned and he is lying on his right hip.

Continuity: When McClane knocks the fridge over so it's on its side near the start, his head is above the top (side) of the fridge. Camera cuts and it is well below the top (side) of the fridge.

Continuity: When McClane tells Matt to get ready to run when in the apartment, McClane's position changes instantly.

Continuity: When Running to the car after the apartment shootout, Farrel gets in the car and McClane is not around by the car as we can see the car. However when Farrel shuts his door, McClane is already in the car. In the previous shot we could see McClane behind Farrel.

Continuity: When the one bad guy has got McClane near the start in the alleyway, there is one shot where the bad guy is facing the other way. He goes forwards feet first for one quick shot then goes backwards to hit the dumpster.

Factual error: In the street scenes of Washington, DC, the cabs are Yellow Cabs. DC does not have a yellow cab system, but rather "gypsy" cabs that come in all colors. There are actually very few yellow-colored taxi cabs.

Continuity: When in the traffic jam, just before the first accidents, the background doesn't move in the shots of Ferral, but it does, and quite fast, in the shots of McClane.

Continuity: In the traffic jam in the beginning of the film (right after all the lights have changed to green), the car next to McClane's is black/dark. But a few seconds later when you see it from a helicopter, it has changed to white.

Continuity: During the traffic jam scene, when the truck crashes against the taxi, the view inside McClane's car shows the taxi colliding against the car, dragging it away violently. From the aerial angle, the taxi doesn't touch McClane's car at all.

Other: The hackers cause a massive traffic jam by manipulating the street lights. Yet, only minutes later, the streets are conveniently empty when McClane is being chased by the chopper. Sure, one or two streets were secured by police, but the chase scene goes through many more streets.

Continuity: At the end of the scene where Bruce Willis's own car is involved with a crash between a dustcart and taxi you can see his driver's door opening during the aerial shot after he has left the location.

Continuity: When McClane first brings Farrell to the Cyber division, McClane has a cut over his eyebrow that he gets from a fight scene later in the film. [This mistake is pointed out in the DVD audio commentary: this scene was filmed after said fight scene was completed. Still a mistake, though.]

Factual error: The "police" radios shown in the police cars are actually amateur band radios on an amateur band frequency.

Audio problem: After the terrorist in the helicopter opens fire on John and Matthew, a policeman yells something about backup into his radio. What he's saying doesn't match up with his mouth.

Continuity: When McClane is driving the police down the ramp to the tunnel so he can elude the helicopter, the car's windshield doesn't have any bullet holes or cracks in it, even though it did just a few seconds earlier.

Continuity: When McClane and Farrell are fired upon during the escort to DHS, Agent Johnson is killed and slumps against the steering wheel. In the next shot he is alive, looking back through the car's rear windshield, and jolts forward with the car's impact with the car in front of them.

Revealing: In the tunnel, as John does the 180 handbrake turn, if you look on the floor you will see skid marks exactly where he performs the 180 turn. Clearly from previous takes.

Continuity: When the truck crashes into the pillar that McClane and Matt are hiding behind in the tunnel, we see a large portion of the pillar fall off from the left side. However, when McClane gets up to drive the police car, the pillar is in perfect shape.

Plot hole: When in the tunnel, McClane gets back into the cop car and leaves Farrell, he drives very quickly. After the helicopter blows up, it is only a few seconds before Farrell finds McClane. Even running at his top speed, Farrell could not have reached McClane's position so quickly.
