Factual error: In one of the scenes in which took place in a white room, on the door behind the character's head is a modern day "door closer". Door closers were invented in 1880 by Lewis C Norton of the the LCN Company and the first one was installed at Boston Trinity Church in 1880, was some 15 years after this film took place.
Factual error: The beginning scene of the film is supposed to be in 1984. An Alf lunch box can be seen being carried by one of the students and Alf wasn't on the air until 1986.
Factual error: The VW Bug that the belfry falls on is a later model than 1965 when the movie is set. The larger tail light with yellow on the lens seen on the VW in the movie didn't come along until 1968. The one in the movie may even be of early 70's vintage.
Factual error: At the beginning of the film you see the car coming around a bend and see a double yellow line in the center of the road. White center lines were used as early as 1917 but weren't widely used until the early 50s and center yellow wasn't mandated until 1971.
Factual error: In the scene where Evan is talking to Sgt. Bressman in front of Costco, you can see that Bressman is wearing Maryland State Police lapel pins. This is incorrect because the movie is portrayed in Ohio.
Factual error: In the scene where the Bellas run out of gas, on their way to the second competition, it shows the gas gauge saying "unleaded fuel only." But when the bus runs out of gas it makes the sound that a diesel engine makes, not a regular gas engine.
Factual error: The Asian girl in the future was wearing her collar with termination charge for a very long time around her neck. When it was removed there was no mark, tan line, or indention or anything left behind, as if it had never been there. Yet all evidence points to years of endless wearing. (01:00:00)
Factual error: When Bella is driving back from Seattle, the speed limit signs say 80. There is no 80mph speed limit road between Seattle and Forks; the movie was filmed in Vancouver and the sign is, in fact, in kph. (01:04:55)
Factual error: When Alma and Whit drive along the coast, the road has recessed center line reflectors. These hadn't been invented yet in 1959 when the movie takes place.
Factual error: When Aladeen discusses how his rocket has to be pointy on the top, the rocket-scientist says: "The shape of the missile top has nothing to do with aerodynamics." This is factually wrong. Nose cone design is very important for aerodynamics. A real rocket-scientist never would say something like that. Stupid Aladeen even could be right with his pointy nose demands (although he fears a bounce back of the rocket not bad aerodynamic characteristics), because most modern missiles do have pointy nose cones.
Factual error: When Ranger takes Stephanie to buy a gun, the one she gets is a 5-shooter, but in the scene where she is firing it at the gun range by herself she shoots it 12 times without reloading. Later, in the scene where she shoots Jimmy Alpha, she fires it 7 times without reloading.
Factual error: John Carter, while gold prospecting in 1868, is arrested by members of the 7th Cavalry, with the intention of employing him to fight the Apache in the Arizona and New Mexico Territories. Unfortunately, in 1868, the 7th was otherwise employed in Kansas and Indian Territory forcing the Cheyenne, Kiowa, and Comanche tribes back on their reservations.
Factual error: On the isolated island, the meerkats stood up and see Richard Parker and then Richard happily eats some of them while the others watch. Meerkats would run away when they sense, hear or see a nearby predator.
Suggested correction: The reason for this is explained in the book. It's because the island is so peaceful they have no reason to fear predators.
Factual error: Ellis and his mom come across a roadblock and police checkpoint of State Troopers checking cars for Mud. The Arkansas State Trooper that comes up to the window is wearing the wrong uniform. His badge is wrong, and his shirt is wrong. He has one of the cloth badges on his right shoulder, but it is the wrong shape for State Troopers. And he has an American flag on his left shoulder. Arkansas State Troopers have the cloth badge on both shoulders, not an American Flag. (00:38:25)
Factual error: The station under Cape Town stadium do not exist. Although the first tram line was from Cape Town to Green Point (the stadium's location) it was discontinued just before world war 2.
Factual error: At the beginning when Heinrich's brother falls from the building there are two mistakes that can be seen. First: The cars are driving on the wrong side of the road. Hong Kong drives on the left just as they do in England. Second: The license plates on the cars are for Mainland China, not for Hong Kong. China uses blue background with white letters, while Hong Kong uses yellow or white with black letters.
Factual error: The movie is set in the current time (2012), but Andy flies in an L1011 in the distinctive paint scheme of Delta Air Lines. Delta retired the last of their L1011 fleet in 2001.
Factual error: In one scene Drew Barrymore stands in from of a political world map, showing the political borders as of today. You can see the successor countries of the Soviet Union in that map. But the plot plays back in 1988, with the Soviet Union still alive.
Factual error: The same car registration is used on several cars throughout the film.
Factual error: At one point in the film, Katniss passes out after being stung by wasps numerous times. When she asks how long it had been upon awakening, Rue answers, "A couple of days." If she had been out that long, and as a result been unable to drink, she would be in very bad condition, not to mention the fact that she would immediately need to use the bathroom.
Suggested correction: You can help an unconscious person stay hydrated by gently pouring small amounts of water into their mouth. They'll swallow it by reflex.
