Continuity mistake: When the LAPD are making the money drop, one shot from Dennis Hopper's apartment shows a businessman walking past the garbage can with a silver briefcase (just as the garbage man comes), and the same man with the silver briefcase walks past about a minute later in another shot when Keanu Reeves is running towards the bin.
Continuity mistake: In the last 20 minutes of the movie when Howard Payne is on the train and offers Jack some money, Howard opens the money bag and gets sprayed with purple paint. When Howard climbs on top of the train to fight Jack, all of the paint is gone.
Continuity mistake: After the bus driver looks at the note "Bomb on Bus" he starts decreasing speed. So Keanu puts the Jaguar beside the bus and tells the bus driver to open the door for him to tell the driver to go at a speed of 50 miles per hour. Just before this you can see a camera shot in which the door is already open. This mistake is easily seen if you watch it in slow motion.
Continuity mistake: When Jack slows down to break the door of the car, he comes to a complete stop but the very next shot, he is back at normal speed.
Continuity mistake: At the end of the film, the train flies off the track, through a wood-framed tunnel under construction, and then onto a city street. During the credits, as the shot is pulled back, there is no destroyed wood-framed tunnel. In fact, traffic is flowing normally in the background.
Continuity mistake: When Harry is talking to a police woman at the station, about going through the police files, the woman's bangs are messed up. When the camera pans back to her, every hair is in place.
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 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: 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: 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: 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: 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 the bus jumps over the gap in the freeway, when they take off, Jack shields Annie with his own body, but when it shows an exterior shot of the bus when they have landed, Jack is gone, then he comes back again in a different shot.
Continuity mistake: After the first bus blows up, Jack hears the phone ringing. It is a two phone stand. When Jack first reaches for the phone to answer it you can see he answers the phone on the right hand side. To the right of the phone you can only see trees to the right side. In every scene after that, he is on the left hand side phone.
Continuity mistake: When Jack and Annie arrive in the ambulance, as Jack leaves the ambulance he closes the side door. However, when Annie gets bored and gets up to leave the ambulance via the same exit that Jack did earlier, that door is now open.
Continuity mistake: Traven drives at high speed down the hard shoulder of the freeway to get to the bus to avoid the big traffic jam. When Traven cannot get on the bus, the black Jaguar XJS is now close at hand, which would have been impossible - it was way back in the traffic and couldn't have got to him that quickly.
Continuity mistake: After Jack discovers the camera, we see what the camera is seeing in Howard's apartment on the screen. Where is Jack? He was just standing next to Annie. He should be front and center in the shot but he is nowhere to be found. The shot is wide enough that even if he was leaning out the door we'd still see him. When we see the monitor again later, he is there.
Continuity mistake: When Jack is under the bus there is a shot from the driver's side that shows the vehicle pacing the bus. The two people that were standing on that vehicle are gone. They are back the next time we see it (when the bolt snaps).
