Continuity: In the scene where Harry has gone to the house of Dennis Hopper, he is able to move around as freely as any other member of the raid team. His limp appears to have disappeared completely, after having changed legs in the bar earlier in the movie.

Continuity: When Annie swerves to avoid the schoolteacher and the kids, in the previous shot of the kids and the schoolteacher, they have already stepped out onto the road and are crossing, yet when the camera cuts to a view looking out the bus the schoolteacher and the kids are just stepping off the curb and walking across.

Revealing: When Howard Payne's house explodes, a wire is visible as it pulls back one of the police officers who gets "blown back" by the explosion.

Continuity: Just after the bus driver has been unloaded and Helen tries to get off, Annie shouts "No Helen" at which point Jack turns around and grabs her shoulder to stop her. The shot switches to Dennis Hopper watching TV and then back to the bus where Jack is no longer even close to Helen when the bomb detonates.

Continuity: When Keanu and Jeff are on their way to the building at the start of the film, their car flies over a hill and lands back on the road. The right hand front wheel takes a really nasty knock as it lands and looks ready to come off, and yet in the next shot they arrive safely with no apparent difficulty driving the car.

Visible crew/equipment: In the scene where Jack is running beside the bus and breaks the window to get the drivers attention, you can see a reflection in the window of the bus of a cameraman running. In the next scene where the bus pulls ahead, the reflection of the camera is larger and more noticable.

Visible crew/equipment: Aside from the mysterious other trooper(s) reflected in the tarpaulin on the roof near the start, as Keanu Reeves runs past it, you can see the clear silhouette and red light of a cameraman filming the scene.

Visible crew/equipment: When Sam is shot in the shoulder it shows a camera shot from the side of the bus going into a wall. In this camera shot you can see the shadow of the camera.

Factual error: When Payne blows the safety catch on the elevator it shows a shot of the floor level indicator going down from 29 to 25 in about 3 seconds. The camera cuts to inside for 5 seconds then the cable stopping the lift. This has taken approximately 8-10 seconds in total, but they are only on the 22 floor now. By the rate of which they were falling they should be on at least the 13th floor. Not taking into account that it would be accelerating as it goes down.

Continuity: 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.

Other: During the scene where Jack and Annie escape from the bus using the hatch door on the bus floor, they lay on it sideways holding on to each other. If you had a chance to look at the bus from various other camera shots during the film the gap between the undercarriage and the runway was too small for them to do this, the rear bumper also seems to hang lower.

Continuity: 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.

Visible crew/equipment: When Jack is talking to Howard from the pay-phone, you can see the boom microphone's reflection in the phone in several shots.

Revealing: When Jack is fighting Dennis Hopper on the roof of the subway train, a peice of paper falls off one of them and then stays surprisingly still considering they're on a speeding subway train.

Other: In the scene where Jack has come back into the bus from being underneath it, he is talking to Annie about losing gas, if you watch closely he says "Mac" without pressing his button to call him first, then in another shot you see him press it when he starts talking to Mac.

Revealing: In the scene where Annie gets told by Jack to turn into the airport, she does so, and, if you watch closely, when she runs over the spikes, the back tire is seen to have run over one of the spikes. But if you slow it down, there is something in the next spike along causing the huge burst of dust and air. This can be seen if you use frame by frame.

Revealing: The chain pulling the first exploding bus is visible.

Factual error: If you look at the loop Keanu hooks the crane onto on top of the lift you can see that it and its bracket have been recently welded on (by the black residue it leaves), obviously because the lift itself didn't have such a loop. Even if such a feature existed, it wouldn't be simply spot welded on the top as this one is, it would need to be part of the lift's structure if it were to serve any purpose in supporting it in an emergency.

Continuity: In the first part of the movie, it appears that the building is approximately 53 floors high, we can see this as when Keanu Reeves and Jeff Daniels go to the roof the label on the door is "ROOF/53". However, the service elevator seems to reach the top of the shaft after Dennis Hopper enters level 46 on the control panel. This is rather unfortunate, especially as the security console says that the elevator "serves floors GE-52". I wouldn't like to be in the elevator as it tries to go past level 46 to a higher floor such as 52.

Visible crew/equipment: When the bus is jumping the gap in the bridge, if you look closely in one shot, Sandra Bullock is not driving. Instead it's a large man that appears to be wearing women's attire.
