Corrected entry: At the start when the explosion goes off, supposedly killing Dennis Hopper, you can see that the explosion actually forms a shape around the door frame and that the wall blows inwards. This is because of the individual charges placed around the door to make this effect work, in fact you can see the holes that they cause. In an explosion such as this, probably the first thing to happen would be for the door itself (the weakest point in the wall) to be blown off rather than the wall coming away with the door in it.
Corrected entry: On the bus, when Jack is reasoning with the guy who has the gun, the black guy tackles, then struggles with him, and the guy with the gun shoots at Sam (the driver). In slow motion, the glass behind Sam doesn't break away and smash, it only shatters a slight bit. A few shots later, when Annie is driving the bus, the glass is now completely smashed and only a few bits remain in the frame. (00:40:05)
Corrected entry: At the beginning of the film when Jack is talking to Howard Payne on the phone he hangs up and runs for 2 seconds, yet in the previous shot he ran quite a distance to catch up to the bus, this means he's very fast at running or someone moved his jeep further up the street. (00:29:30)
Corrected entry: If you look at the bus jumping in slow motion, you will see that there is no-one inside the bus.
Corrected entry: Right after Jack discovers the camera mounted on the bus, Payne is seen drinking and watching the news. The anchorman on the far right of the screen says, "Amazing story as a city bus, rigged to explode if it slows down, races around literally in circles at the Los Angeles Airport. The two dead are a female passenger and the driver of another bus, both blown up by the bomber. And the other people in jeopardy are of course the passengers on the bus, held hostage at the whim of a madman." The female passenger was of course the woman who tried to get off the bus after Sam was let off, but the "driver of another bus" was obviously Sam. Number one, the only bus we know that Sam drove was number 2525, the same bus. Number two, he may have died of his wound, but we never find that out specifically. Number three, he wasn't blown up by Payne - another passenger on the bus accidentally shot him earlier in the film. (01:24:30)
Corrected entry: Dennis Hopper is using a "Dead man's handle" type device, if he dies or is incapacitated, or the control just plain falls out of his hand then the bomb will detonate. Ironically a common use for these devices is in the safe control of trains, if the driver doesn't keep hold of a certain handle or regularly press a button the brakes kick in automatically. Most trains built in recent years in the Western world have them (eg. Channel Tunnel trains), yet curiously the brand new train in LA carrying Sandra, Keanu and Dennis doesn't have one, the driver is dead but the train carries on.
Corrected entry: When the bus jumps the bridge, if you look closely inside, you can see there's no passengers on the bus.
Corrected entry: When the "tourist" in the blue jacket is being transferred from the bus to the rescue vehicle, he falls down and has to be pulled up. You will notice that his jacket is torn on the back, but when he is seen on the rescue bus later on, the tear is gone.
Corrected entry: In the scene where the bus crashes into the plane, you can see that the plane is a cargo plane. However, as the plane blows up, you can see that a big piece of fuselage (plane structure) that has window holes. Cargo planes have no windows or at least not that many.
Corrected entry: At the part where the lady tries to escape from the bus and the bomber triggers a smaller bomb to go off, the bomber relied solely on the live TV telecast. In real live TV, it takes time for the transmission to go from the camera, to the station, and to your TV (usually about 3-4 seconds). In the movie, the bomber gets his timing perfectly correct, but in real life the lady might've already had most of her body on the other truck and only would suffer injuries rather than death.
Corrected entry: At the beginning of the movie, after Keanu finds out about the bomb on the bus and that once the bus reaches 50 mph, dropping below that speed would detonate the device. We see him make a mad dash to reach the bus before it attained the initial 50 mph speed. He reaches the bus and runs along side it banging his fist on the door. The driver apparently thinks he is a lunatic and continues on. We then see Keanu draw his firearm and commandeer a civilian's vehicle at gunpoint to begin pursuit of the bus. This leads us to believe that a trained police officer with a firearm in his possession, and running alongside a bus trying to keep it from reaching a speed of 50 mph, would not simply shoot the tires out. I would, and I'm not even a trained police officer.
Corrected entry: In the scene where the villain has Sandra Bullock hostage aboard the train you can see that his hands have purple dye on them before he has actually even opened the bag of ransom money containing the purple paint bomb. His hands should be clean at this point as the paint bomb has not yet exploded.
Corrected entry: When Jack comes up with the idea to hold the elevator with the cable and says that he has an idea, Harry says "You're not going to shoot them are you?" The next scene has them on the roof and Jack answering "No, we're just going to take them out of the equation." Sure, that seemed good while watching the movie since the answer came just seconds after the question. But in reality, they had to climb out of hte elevator shaft, and run up 20+ flights of stairs. This would have taken at least 4-5 minutes. So why is Jack just answering this question NOW, and why does he answer it as if it was just asked?
