Corrected entry: How did Payne not find out about the passengers getting off safely sooner than noticing the loop in the video feed? While choppers weren't allowed in the air space of LAX, there was reporters and media following the event on almost every channel. Payne was watching numerous TVs but not one channel mentions the massive explosion at the airport when the bus hits the plane, which would have been visible from the perimeter.
Corrected entry: In the subway car scene, the voice calling for "Westbound 501" is distorted, as you would expect from a CB radio. Later on when Mac calls on the same radio, his voice is much clearer, as if he's right there.
Corrected entry: In the scene after they get to the airport where the news helicopters can't follow, Keanu Reeves talks Dennis Hopper into letting him get off the bus to talk to the money people. They cut to Dennis Hopper with several TVs in the scene. The bottom right TV still has arial coverage of the bus.
Corrected entry: During the final scene when the train car crashes onto the road, the way the glass shatters into very very small fragments indicates that it is not real glass, and likely sugar glass.
Corrected entry: A bus would never, ever be able to maintain a speed of 50 mph on the secondary streets of Los Angeles in the middle of the day, for any significant length of time, without smashing into hundreds of other cars (in which case, it would probably drop below 50 and explode anyway.)
Corrected entry: In the highway scene where the older female bus passenger panics and attempts to leave the bus by getting on the flatbed truck driven by the police, right before the explosion that kills her occurs, you can see Keanu Reeves grab her arm for a split second. There is then a cut to the explosion, then another cut back to Keanu lying on the bus floor with his arm outstretched, having ostensibly been unable to grab the lady in time.
