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. (00:13:45)Ssiscool
Visible crew/equipment: When Jack is running beside the bus and breaks the window to get the driver's attention, there's a reflection in the window of the bus of a cameraman (wearing a baseball cap) running alongside the camera. In the next scene where the bus pulls ahead, the reflection of the camera is larger and more noticeable. (00:34:35)Melissa
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.
Factual error: At the airport, Jack attempts to disarm the bus bomb from underneath, on a dolly towed by another vehicle. Meanwhile, Annie must continue driving the bus in circles on the runway at a speed above 50 mph. This scene takes 8 minutes, meaning Annie makes at least 2 laps of the entire 2-mile-long runway, complete with turns at the ends. There is no way that the towed dolly could remain positioned directly underneath the bus through the turns, as Jack would have swung out under centrifugal force.Charles Austin Miller
Continuity mistake: At the start when Jack is trying to get on the runaway bus, he is seen passing the guy in the convertible Jaguar on the freeway entrance-ramp. He continues to overtake lines of stationary traffic in order to catch the bus, and then pulls alongside it. In the next shot he commandeers the Jaguar so he can use it to get onto the bus; however the Jaguar should still be waiting in the queues some way behind. (00:32:55 - 00:35:00)
Visible crew/equipment: In the scene where the bus is exiting the highway on that sharp curve there's a medium shot showing the bus from the driver side. Look closely at the driver, it's either a really ugly woman or that's a man in a wig driving the bus. (00:47:04)
Visible crew/equipment: During the scene where the bus takes the really sharp curve it kind of goes over on two wheels - if you look closely, you can see some sort of lift under the bus obviously causing it to tilt so far sideways. (00:50:10)
Other mistake: 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.
