Factual error: In the final scene, when Jack Sparrow is looking at the map to find the Fountain of Youth. The map lists Ponce de Leon's travel date of 1523. The actual date of the Fountain of Youth founding was 1513.
Factual error: When they take the General out of the water, they rebuild it from the ground up. They are somehow able to do this in maybe a couple of days which would be impossible seeing as how it was in the water. They would need to sandblast the rust, reprime the bare metal, and repaint it which would take more than 2 days alone, plus there were only Bo, Luke, Daisy and Cooter working on it.
Factual error: During the police chase, the helicopter calls in a car approaching at speed behind the police cars, but he calls it a "late model Trans Am." The Trans Am is an early model at best, as it is a 79 to 81 second generation (of 4) Trans Am. A late model Trans Am would be more accurately described as one of the fourth generation models built until 2002, and look nothing like a 79 to 81, even from the air. It might be considered a character mistake, except that police are generally knowledgable about the make and style of cars from various years. If the pilot or passenger of the helicopter were able to identify it as a Trans Am, they should be able to identify it as an older model, not a late model.
Factual error: The second part of the movie is supposed to be located near Lebanon, TN, however, it is fairly obvious the terrain is Southern California. I realize that movie companies often use different locations to film than what they really are, but the landscape between CA and TN is vastly different.
Factual error: At the scene in the church, there are lots of security personnel standing around wearing steel helmets. The helmet type seems to be an East German M56 helmet (standard for the East German Armed forces until reunification). There is no reason why a Russian security force would have the M56 helmet. (Only if the makers of the movie where able to purchase a lot cheaply :).)
Factual error: Doomsday sees a little girl crying in the street and stops his assault on Superman to go attack the little girl. Superman quickly grabs Doomsday around the waist and jumps, rocketing them both up into space before Doomsday can crush her. The shockwave of this jump is seen as the tremendous force causes the street they were standing on to break apart and rubble fly. Yet the little girl is completely unaffected by the shockwave, it passes right through her and she is only feet away from the crater now left from Superman jumping up with Doomsday. (00:25:20)
Factual error: In the control room, the TV monitors show Vinnie Jones face against a background of the British flag. It is upside-down.
Factual error: When they are trying to escape by helicopter 2 fighters pop-up and shoot with their machine-guns on the snakes head but when you see close up its raining bullets on their heads while those 2 planes are floating next to the building not above it.
Factual error: After Carlton Leach and his friends have been tricked by the kids, a huge fight starts, and police arrive to break it up, a Ford Sierra is seen in the background. The fight is set in 1982, but the model shown is from the early 1990's - impossible for 1982.
Factual error: In the intro sequence of the movie where they show old clippings and all, the animation part depicting the sep,11 incident seems to be wrong. A plane is shown moving towards the south tower while the north tower stands clear of smoke. In the actual incident, the north tower took the first hit. The north tower in the animation can be identified by the antenna. (00:03:10)
Factual error: No army flight from Georgia to Iraq would cross central Mexico.
Factual error: Early in the film, Chris foils a casino shooter, steals a car, and leads police on a high-speed chase through Las Vegas. He has a psychic vision of himself being smashed into oblivion at a railroad crossing, so he knows he must accelerate to 120 mph to beat the train. The camera cuts to a head-on view of the train, and this time Chris goes flying over the crossing, just barely missing the train. Oddly, there are no barricade arms with warning lights at the railroad crossing, even though this train is screaming through an urban area. Additionally, the car is already levitated about 3 or 4 feet in the air long before it ever reaches the railroad crossing, as if it hit an invisible launch ramp. Thus, Chris makes his escape as the train blocks any further police pursuit. We then see two angles of the fleeing vehicle suddenly make a hard left turn down a side street about a block past the railroad crossing. Which is physically impossible. Given that he air-jumped the railroad crossing at 120 mph, Chris could never have slowed down enough to make a hard left turn within one block. It would require more like 10 blocks to slow down to a manageable turning speed, if he could regain control of the car.
Factual error: SSgt Gallegos asks Carter what other ammo he has, and he responds 5.65. No such ammo exists - M16/M4 uses 5.56 rounds. (01:17:41)
Factual error: The Human Torch chases the Silver Surfer into the Lincoln Tunnel at 29:35; the entrance shown is on the New Jersey side of the Hudson River (although they had just been in Manhattan seconds before, they were airborne and could have gotten there from the sky). When they collectively exit the tunnel at 30:01, they are still on the New Jersey side, as evidenced by the toll booth clerk who witnesses their flyby. While both the entrance and exit scenes are physically in the same a place, a large American flag was either pasted into the entrance scene or edited out of the exit scene, creating a slightly different visual element to two otherwise identical landscapes.
