Continuity mistake: At the beginning of the movie after Jack has hooked up the crane from outside to the lift, there is a shot of the crane outside, and the line going through the vent. If you look closely there is a pipe in front of the vent, yet when the crane goes through the vent, the pipe has vanished. (00:14:20)
Continuity mistake: Jeff Daniels' character gets shot in the thigh by his partner. Later, when he gets his award, it is the opposite leg that has a cast on it.
Continuity mistake: When Howard Payne is in the elevator, he hears Jack and Harry doing something from above, and he reaches for his bomb trigger. In slow motion when he's picking it up, it has two buttons on it, yet when Howard pushes one of the buttons, the device now has three. (00:13:00)
Continuity mistake: When Jack is chasing the bus on the freeway in the Jaguar, an overhead shot is shown of the bus with three cars around it, but in the next shot of the traffic, the road is full of traffic which is surrounding the bus, which is highlighted by Jack having to swerve around the cars.
Continuity mistake: When Dennis Hopper's shooting the shotgun through the lift roof, the number of holes doesn't match the number of blasts. He shoots once and a hole appears. We then see a close up of him and he shoots twice more, but when we cut to the ceiling after the third shot overall, there are only two holes in it. Doesn't seem likely he'd miss the roof at a range of 2 feet. (00:18:55)
Continuity mistake: Near the end of the film when Keanu Reeves and Dennis Hopper are wrestling on top of the subway, if you watch Keanu's left wrist you notice he is wearing a watch. Yet throughout the scene it is obvious that the stunt double has no watch, because in the extreme action scenes, there are no signs of it anywhere on his wrist.
Continuity mistake: On the subway train where Payne opens the money bag, a dye pack goes off and leaves a purple stain on the dead man's handle. But moments later in the shot where Payne stops firing his machine gun at the ceiling, the stain has vanished. (01:42:35)
Continuity mistake: When Jack handcuffs Ray to the metal handrail, Ray's right wrist has the double strand bars facing up and single strand bar facing down, but when Jack tells the passengers about the gap and then uncuffs Ray before the jump, the handcuff's single strand bar is facing up on his right wrist.
Continuity mistake: The 2 SWAT team members are not visible on the preceding truck between two shots. (01:12:55 - 01:13:32)
Continuity mistake: Right after the bus jumps the gap, Jack hugs Ortiz. Immediately following you can see the reflection of the stairwell at the front in the mirror. The stairwell and door are both fine, after having been blown off when Helen died. (01:07:00)
Continuity mistake: When Jack starts wiggling the train's pole, his hands switch places between shots. (01:46:05)
Continuity mistake: As Annie shouts at Sam and suggests he drive over the line of cars up ahead, the bus passes by a couple of bridges - visible through the side window where she and Helen are seated. But no bridges were visible anywhere at all when Sam first noticed the endless line of gridlocked traffic just seconds before. (00:33:55)
Continuity mistake: At the very start of the movie, in the basement, you see a security officer walk past some numbered steel pillars, he walks past the pillars numbered "15" twice. Fixed in the Blu-Ray. (00:03:35)
Continuity mistake: After the bus has left the freeway and enters the city for the first time, there is a scene where Annie is driving the wrong way down a street and Jack can be seen standing right next to her. She pulls the bus onto the right side of the road and Jack puts the cell phone to his ear. In the next shot, he repeats the same action.
Continuity mistake: In the scene where Jack is fighting Dennis Hopper on the roof of the subway train we see Jack lying on the top of the train getting punched by Dennis. We briefly cut away, and then back to Jack and the corrugations on the train roof have rotated through ninety degrees.
Continuity mistake: In the scene where the plane is blown up at LAX, the intact plane is shown with no mountains in the background. However, the scene showing an exploding plane has a backdrop of desert mountains, presumably Antelope Valley California.
Continuity mistake: In the scene where Jack drives the car backwards so he can tear off the door, enabling him into the bus, he slams into a silver car. The very next shot, maybe two seconds later, there is another car driving behind him like nothing happened. (00:39:15)
Continuity mistake: When Jack is running across the street in downtown Los Angeles, in two different camera shots two different red cars are shown stopped in the same place to let him cross the street.
Continuity mistake: When Jack and Harry are pulling people out of the elevator there are two men offering to help the stubborn lady out of the elevator. 2 seconds later there is only one man jumping to get out. (00:15:50)
Continuity mistake: When Keanu Reeves is on the payphone with Dennis Hopper, his lips appear increasingly redder throughout the scene. (00:28:00)
