Factual error: Given the destruction from the nuclear blast threw the truck in the air, the rest of the surrounding area would also have experienced similar destruction. However when they are walking away from the truck to another town in a nearby field, there is no visible impact of what was a recent nuclear explosion anywhere to be seen.
Factual error: In the scene where they are in the U.K, a little boy is hit by a van and you can hear the police and medical services coming. The sirens are American sirens which differ greatly from the High Low pitch that the U.k Is famous for and do not fit the scene at all.
Factual error: In a very early scene, just as the young girl is pulling a cellphone out of her vagina, if you look closely you can see that the "cellphone" she is holding is actually an iPod Nano 5th generation, which does not make phone calls. (00:04:20)
Factual error: All propane tanks for the last 30 or so years have a safety valve which prevents them from simply releasing gas when the valve is turned on. Given these tanks looked brand new and Jake only turns them on, the gas would not have been released.
Suggested correction: The propane tanks they use are PEN15 models and the safety mechanism is easily circumvented.
Factual error: When they are watching the prince's wedding on TV, you can see the TV-channel's logo in the corner of the screen. The channel NRK didn't start using this logo until 1996, so the program is definitely a rerun, and not the original airing from 1968 which is when this film is set.
Factual error: Towards the end of the movie where they finally can get on the bus the bus scene has two mistakes. One is that it travels ilegally on the right hand side of the road at speed over some chevrons but more importantly as they are supposed to be in Tipperary, there is a bus stop sign which says "Dublin City Bus" which is a completely different bus service to the "Bus Eireann" service they get on.
Factual error: Just after the scene from "the picture frame store" with Jason Bateman and Jeff Goldbloom, there are a few shots of New York City. One of the shots features the twin towers of the old World Trade Center. (01:08:30)
Factual error: Rita says that George was a gunner in the RAF during the war. The photograph of him in uniform in his and Connie's house shows him wearing a (double wing) pilot's brevet instead of the single wing of an air gunner.
Factual error: The attack on the OPEC meeting in Vienna takes place on December 21. Yet, when Carlos' team exits the tram, the trees are full with green summer leaves and the sun shines as it would on a high summer day.
Factual error: When Phil Foster and the cabbie are trying to access the files on the flash drive, they use an Amazon Kindle. The Amazon Kindle does not have a USB connection for a flash drive.
Factual error: There's a scene where a woman's son and Kahn are playing on an Xbox. The movie was set around the time when 9/11 happened and the console was not even released at that time. You can tell from the controller they were using. It was white and had a battery underneath for wireless gaming.
Factual error: In the part near the end of the movie where the agents are told that they must push a kill switch to thwart Kitty Galore's satellite launch, Butch says "Look - that red button! It looks like an off switch." Butch is a dog, which means he is color blind. Doubly odd as in the first film Butch does mention that he is colorblind and cannot identify a red wire when he tries to defuse a bomb the Russian cat attached to the lab door. And yet, he claims the whole time that he's colorblind, when dogs aren't actually colorblind anyway. They only have a minor coloring difference, and they have somewhat poor eyesight.
Factual error: Towards the end of the movie when the woman with her daughter, Tuti are building the house on the shore.she was putting the tiles of blue on the sand, no foundation and they were building the walls on the tile, when building a house tile is the last item that is put in.
Factual error: In the chase scene where Lou is running after the derelict, they pass a number of vehicles parked and driving on the streets. All of them are correct period vehicles for the late 1950s, except for a white semi truck which is from at least the mid 1990s. The grille and headlights on the truck are the giveaway. (01:23:20)
Factual error: Farmer MacReadie tells Phil he knew of a pig that could play Scrabble. However Scrabble was not released until 1948, three years after the war ended.
Factual error: When Jamie Lee Curtis drops the earring down the drain, she panics and kicks the pea trap off the drain. This causes water to spew from the pipes which is possible if she accidentally kicked the water pipe but when she replaces the pea trap by hand, the water cuts off which would not happen, as the drain has nothing to do with running water.
Factual error: A delightful movie that theoretically takes place in the vicinity of Portland Oregon, over a period of many months. The problem is, that at no time does it ever rain, and anyone who has lived near Portland knows it rains half of the year.
Factual error: Edgar's license plate is "FROG BROS", but California only permitted up to seven digits at that time. It wasn't until 2014 when eight or nine digits were permitted, but even then only in "very rare cases." (00:27:40)
Factual error: Sergeant-Major Saunders is wearing sergeant's stripes. Corporals Drake and Levin are wearing no rank insignia at all.
Factual error: While measuring the Electromagnetic Field (EMF) being given off by Stonehenge in the film, a scientist exclaims that the frequency is increasing to over 100 Gigahertz, and is approaching radioactivity. This is absurd. EMF is radiation of electromagnetic waves over a wide spectrum of frequencies. Its strength depends on the frequency at which it is measured, with no relation to radioactivity whatsoever. It has a magnetic and an electrical component, but no nuclear breakdown as such.
