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. (00:11:30)
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)
Visible crew/equipment: In the scene where Jack is taking off the handcuffs of the guy who shot Sam, you can see the top of a bald crew member's head with headphones on behind them.
Continuity mistake: When Jack and Mac are on the back of a truck with the red cart tied to the back of it, when Annie says "I have no idea", Jack and Mac both have their backs against the truck facing the camera, but in the following shot they are facing each other. (01:09:35)
Continuity mistake: When Annie is running for the bus, she passes notice boards as such, yet when it cuts to a side shot of Annie at the door to the bus, the massive notice boards have suddenly disappeared and all it is now is bushes and gardens. (00:29:45)
Continuity mistake: 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. (00:06:00)
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.
Continuity mistake: When the bus hits the back of the car on the tow truck, it appears that the hit is hard enough to launch the car up the ramp and over the front of the truck, but there is no damage to the front of the bus.
Continuity mistake: When Annie hits her head after jumping the gap on the road you can see a cut. The cut changes shape throughout the whole movie.
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.
Visible crew/equipment: On the train, Jack hears Mac saying the track isn't finished, then Jack becomes aware of the broken emergency stop button. When Jack walks back over to Annie and tells her they have to jump, we can see the reflection of the standing camera operator on the right door's window, and the reflection of a crouching crew member (possibly boom operator) on the left door's window. Definitely crew given they're meant to be alone on the train. (01:45:55)
Continuity mistake: Shortly before the bus gap you can see an END sign at the end of the road. This disappears a second later. (01:03:11 - 01:03:36)
Continuity mistake: When Jack tells the other cop to "turn it on" in reference to the money tracker, soon as they realize Payne has the money, and Jack runs out to the garbage can, the red car that screeches to a stop to avoid hitting him is a red Ford Tempo. In the very next shot from the opposite direction, it's a red Mazda Protege. (01:36:55)
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: When McMahon is in a helicopter trying to guide the bus from downtown traffic onto a vacant freeway, the bus passes through the same neighborhood twice from one overhead shot to the next, roughly one minute later (pay attention to the recurring trio of flagpoles on the right, as well as a pair of cars that the bus overtakes). (00:48:55 - 00:49:45)
Visible crew/equipment: When Harry's colleague hands him a printout of Howard Payne's newspaper article, a boom mic reflection is visible on the window right above the bomb schematic diagram. (01:15:15)
Continuity mistake: When Jack is inspecting the bomb from a red trolley connected to a tow truck, a spool of cable unwinds and breaks free from its clamp, leaving Jack to fend for himself. Soon, McMahon and Norwood are riding alongside the bus trying to see if Jack is okay, but notice how the cable has reattached itself to the empty spool. (01:16:30 - 01:17:30)
Visible crew/equipment: A film truck with its crew and equipment is briefly visible in the reflection of a red van four shots after Jack directs Annie onto the shoulder (use pause to get a better look). (00:46:15)
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)
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.
