Continuity: 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: 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 to swerve around the cars.

Continuity: 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.

Visible crew/equipment: The side camera is visible when the bus has to make the tight right turn. After the bus returns all the wheels to the ground and before it smashes into the cop car, you can see the side camera.

Continuity: 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.

Continuity: 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.

Continuity: 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: 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: 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.

Continuity: 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: 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: When Jack is on the bus and is coming up to the construction site, if you look out of the bus to the left the scenery changes, from having grass on the left before the construction site, to having dirt between shots.

Continuity: 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: In the scene in the subway Denis Hopper has again used an explosive jacket like that used at the start of the film, which is detonated if the remote trigger is released. However when on the subway train, Denis takes the remote back from Sandra Bullock and it is seen that the trigger is quite obviously released and Denis pushes it back in.

Continuity: When Jack has caught up to the bus on the freeway then asks the driver to open up, the driver starts driving off, and Jack tries to catch it but fails. When he is standing on the freeway, look behind him, the red car with its passenger window down is driving past him, but in the following shot the red car is there again swerving to avoid him.

Continuity: When Howard Payne gets off the elevator with Harry held hostage, Jack walks off the elevator and there is a light on the wall that Jack passes twice and/or turns the small corner twice.

Audio problem: When Jack is under the bus trying to diffuse the bomb and the piece of rubber hits him he says "F*ck Me" but his lips don't move.

Continuity: When Keanu Reeves is on the payphone with Dennis Hopper, his lips appear increasingly redder throughout the scene.

Factual error: The Boeing 707 freighter that gets blown up by the bus bomb is obviously a "scrapped" plane (A plane that has lived out it's usefulness and is being readied to be scrapped). One good way of telling this is the plane's exterior shows heavy weathering wear from being stored a long time. But someone told me the way it looks could also be a hasty paint job using ordinary house paint. Either way, still something to look for.
