Revealing mistake: As the bus makes the impossible right turn at high speed, you can see the outrigger wheels underneath to stop the bus going over.
Revealing mistake: In the scene where Payne is waiting for the money to be dropped into the bin, he looks through the blinds out onto the street. When he lifts up the blind with his 'bad' hand, you can see his fingers and thumb taped up out of the way.
Other mistake: Just after the police close the roads in front of the news crews and the black police chopper lands in the road. There is a scene where the bus passes under a flyover with a police escort but the police car in front of the bus nearly stops, making the bus brake hard and nearly stop, bringing it well below 50 mph.
Factual error: Near the end of the movie, the villain shoots the operator of the subway car. In all rail transportation situations I am aware of, an operator falling from his seat would immediately cause the train to slow to a controlled stop. It's called the "dead man's switch." Obviously does not happen in this movie.
Factual error: According to the TV announcer, the bus went from the Santa Monica Freeway to Western Avenue to the 105 freeway. Two problems would have occurred. First, the Western Avenue exit from the SM freeway is way too narrow to safely make a turn at such high speed. Second, there is no onramp from Western Avenue to the 105 in any direction.
Continuity mistake: The bus hits many cars in the movie, yet there is virtually no damage sustained by the bus throughout.
Audio problem: When Annie asks Jack what the plan is, he says something like, "Stay above 50," and we hear Annie reply, "Nice plan," but her lips don't move.
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.
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.
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.
Visible crew/equipment: The first bus explodes, and the traffic on the road mysteriously disappears. If you look down the road, there are construction barriers blocking off the entire road, which would not allow any cars to drive through.
Other mistake: When 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.
Visible crew/equipment: In the scene where the bus jumps the gap in the freeway, as the bus lands, the interior camera jerks down and we clearly see the cameraman's brown shoes.
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.
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.
