Factual error: After the explosive decompression of the JPATS B727, and the captain's initial recovery, he tells the crew, "Look at your charts... See if there is any airport we can make." The F/O looks right down at his reference and says there is "nothing close." Then the second officer is seen looking through his flight charts. Without skipping a beat, he replies that, "there is a road, 20miles ahead." Since they have lost two of three engines on the 727, the captain doesn't hesitate and commits to an emergency landing on, "this road." Also, at this very moment, the "road" in question is not even in sight. The problem with this entire situation is that there are no roads, highways, ETC on flight air charts. Above the clouds, no one in this cockpit would have had the slightest clue that there was a road below, its distance, width, etc. (00:20:20)
Visible crew/equipment: At the end of Maria's interrogation scene at her apartment, as she shuts the wooden door you can clearly see the reflection of the cameraman in her diamond-shaped window. He's the one wearing the gold watch. (01:02:00)
Audio problem: When Noah and the rest of the gang are chasing the Chinese man, Noah is the only one on foot. He sees the Chinese man get in a cab and calls for backup. The rest of the gang arrives seconds later. As Noah gets into the SUV, the sound of the car door closing can be heard before it actually does close (and it never really does in that scene). (01:19:20)
Visible crew/equipment: When the dark car is backing up to park at the entrance of the cemetery and keep watch, you can clearly see the cameraman in the reflection of the right side rear window. (01:23:25)
Continuity mistake: In the scene where they are talking to Snipes girlfriend. Downey says he killed them with his bare hands and shows her a picture of a guy shot twice in the chest.
Continuity mistake: Jones is following the guy with the green cap in a yellow cab into the graveyard. For one shot the hubcaps on the cab are missing. The next shot they are back.
Continuity mistake: During the shootout at the cemetery, when the Chinese sniper on the roof rushes to a new sniping position and takes aim, in the next shot when he is firing, the rifle has swapped from his left shoulder to his right.
Continuity mistake: In the scene at the cemetery, Snipe's girlfriend arrives in a 1995-1997 model black Lincoln Town Car. When they begin to escape the cemetery & the back window is shot out, that car is a 1990-1994 model Lincoln Town Car. As the car speeds through the cemetery it returns to a 1995-1997 model. When it then crashes with the Suburban at the cemetery entrance it has once again turned into a 1990-1994 model.
Factual error: During the plane crash scene, the vertical stabilizer snags a hydro line, which rips it off. There is no way that the tail of a commercial jet would be so fragile. It is far more likely that the lines would snap.
Continuity mistake: In the scene where Tommy and Wesley fall into the grain hold in the ship, the bulk grains flow into a container, in this case the ship's 'hold' and their surface is perfectly smooth from top to bottom. Watch for the incredible number of 'dents' in the smooth surface ('footprints' from previous takes) when the shot changes to Wesley and Tommy fighting, after the flow of grain is turned off. (They've been fighting from the top of the pile down, it occupies roughly the bottom 50% of the screen.)
Continuity mistake: In the scene where Robert Downey, Jr. is accosting Wesley Snipes, in the hospital, Rob rips the EKG leads off of Wes' chest and the monitor goes to asystole (the flatline tone). Then after Tommy Lee Jones dispatches Rob and turns to talk to Wes, you can hear a normal sinus rhythm on the monitor.
Continuity mistake: When TLJ meets RDJ for the first time TLJ takes RDJ gun. He then hands it back, and from 3 different shots we see RDJ open his jacket to put away the gun 3 times
Continuity mistake: In the scene where Wesley Snipes jumps off the building on to the moving train. When he is sitting on top of the train, an aeroplane in visible in the background. The shot changes to show Tommy Lee Jones looking annoyed and then changes back to Wesley Snipes. The plane is away and not enough time has passed for the plane to have flown away.
Continuity mistake: When Wesley Snipes makes the truck rush the roadblock, one of the deputies is not in the patrol car. That car is pushed quite a distance, before it rolls down an embankment on the far side of the bridge, but somehow the deputy not in the car manages to reach his partner in the car nearly straight away and help him out. He must be some runner to be able to get that distance so fast.
Audio problem: In the scene when the plane slides down the hill into the water you hear the classic Hollywood sound used for jumbo jet engines dying out by hitting water. The problem lies in the fact that that engine would have been off by then, either by impact, or by the planes automated systems. Even if it was somehow still running you don't hear it until it dies.
Continuity mistake: When the green Suburban is going to the graveyard, watch the rims, as the scene changes from the Suburban to the graveyard, the rims (on the green Suburban's wheels) continually change from Chevy rims to GMC rims.
