Factual error: As Ben is clinging to the staircase while it is falling apart, there is a close-up of a nail being pulled out of the wood. This nail is round-headed, rather than square as it would have been over 200 years ago. It's also shiny instead of rusty, which indicates that it's galvanized. Galvanization as an industrial, metal-preservation process was not patented until 1837, and was not used in building materials until well into the late-1800s. Since the film states the staircase was made by "the Founding Fathers, " and there was no galvanization of iron nails in any industrialized nation in 1780s-1830's, this is a huge anachronism.
Factual error: After calculating the amount of water they have available Townes and A.J. announce they will be living on "a pint of water per person per day". One problem - they'll be dead within three days, if they manage to last that long. A GALLON - eight pints - a day is the absolute minimum in conditions of dry, extreme heat such as they are experiencing, and that is for a resting male. Take their strenuous exercise into account and you can push that up to two gallons a day. One pint a day? Forget it.
Factual error: In the scene immediately following Harry and Hermione's travel back through time, she tells him, "It's 7:30." The clock, however, is striking the bells for an hour, not a half-hour. (01:43:45)
Factual error: When they're first entering the whaling camp, a penguin startles Miller. That penguin was a black-footed penguin, which is a bird native to much warmer climates. If that little guy had actually been in Antarctica, he would have died within minutes. (00:20:40)
Factual error: When hero boy and girl and Billy are on the runaway car at the north pole, they crash into the stopper at the end of the tracks. They are flung backwards when in reality, due to inertia, they should have been flung forward into the guard rail.
Factual error: When Sam climbs outside the ship he grabs the frozen metallic pipes and rails with both hands - one half covered with a glove, one is bare. He has no problem gripping the cold metal and he can get his hands free every time. If the moisture froze before contact, his hands would be frozen too, so that can't be the reason.
Factual error: Near the beginning of the film there is a map of Europe with the countries coloured in using their respective flags. Great Britain is coloured with the Union Jack (Union Flag) pattern but so is the Republic of Ireland (Eire). The Republic of Ireland is not part of the United Kingdom (the political state) or Great Britain (the geographical term for the island), only the British Isles - they are a separate country and the Union jack is not their country's flag. Only the north or the Irish landmass (Northern Ireland) and Britain should show the Union Jack. If they are using an "old map" it would have to be very old, before the 1920's.
Factual error: After the scene where they fall over the waterfall, and go through what they have left of the equipment. Bill, the Latino doctor, holds up the CD-reader from a desktop computer and says that the hard drive is broken, which would be OK if he actually had the hard drive present. (00:34:35)
Factual error: When Professor Broom puts the old pieces of paper together, the text translates to "Graveyard 16", not "Sebastian Plackba 16".
Factual error: I normally wouldn't bother with this sort of nitpicking, but this film specifically claims to be historically researched - and it's full of historical blunders. For a start, the film is set as the Empire withdraws its last troops from Britain - which was in 407 AD. Now Artorius Castus was a real Roman officer who really did command Sarmatian foederati at Hadrian's Wall, but he died around 200 AD. Cerdic was a real Saxon warlord who did go raiding the Britons with his son Cynric, but he did this in the early 500s. Pelagius really was tried for heresy, but he was acquitted and died of old age; the trial was a decade after this setting, and in the fifth century you couldn't be executed for heresy anyway. Also in the fifth century the Pope had no authority over Imperial troops. I could go on and on but that will do for now.
Factual error: The scene where Nicky is picked up in Amsterdam is not in Amsterdam - the skyline does not match that of the city.
Factual error: As the Hood approaches central London in Thunderbird 2, they fly through Tower Bridge and over HMS Belfast, approaching from the East. However the onboard display in Thunderbird 1 shows TB2 approaching from the West, somewhere over Hammersmith.
Factual error: The race ends at Damascus, which is nowhere near the ocean, yet is placed on the seacoast.
Factual error: When the plane is attacked by missiles, Helen punches a button on the cockpit console and a screen lights up that says "chaff". The next shot shows the rear of the plane with several burning items coming from it that are supposed to be chaff. However, chaff containers burst open into thousands of radar-reflective strips that are meant to confuse radar-guided missiles (see real chaff in the movie Air Force One). What actually comes out are flares that burn extremely hot to confuse heat-seeking missiles. While it might be suggested that we just never see the containers burst open, later in the missile chase we see the exact same items in view for a much longer time and they never burst open.
Factual error: When Derek is calculating how much explosive Mentos to put in Cody's mouth to get the microchip out, he says to himself, "a thousand nanograms equals 1 microgram". While this measurement is correct, it is highly unlikely that any explosive would be of use in even milligram quantities. So 1/1000 of a milligram (a microgram) would be virtually useless, and measurements of 1/1,000,000 of a milligram (a nanogram) would be even less than useless. He couldn't have been calculating explosives in such small quantities. As well, Mentos mints are about 37.5 g (http://home.socal.rr.com/mentosfaq/candies.html), and he then cuts it into approximately 1/8 - micrograms would measure 1/250 of a mint, and nanograms would be 1/2500 of a mint.

Factual error: This may have been considered before drawing it this way, but it's a mistake nonetheless: When Tinkerbell shows up at the end with all the other Disney characters to watch the movie, she is back lit and silhouetted just like everyone else, and so is the pixie dust she is trailing. This is done simply to resemble a dark theater full of patrons, not to play some sort of impromptu guessing game. Her pixie dust has always been luminescent so it should not appear as a shadow against the theater screen. It'd be impossible to be silhouetted to that degree if it gives off its own light.
Factual error: When the children jump off the remains of Aunt Josephine's house, they jump further than they'd be able to. The slanting floor, at least, would reduce the distance, plus they didn't take enough of a run up to jump the gap.
Factual error: The hairy girls claim they are in a giant Redwood named Earthchild. The only Redwood trees in Oregon are in the far South West corner very near the coast and mostly over the border of California. D. B. Cooper was supposed to have landed North of Portland. (00:57:40)
Factual error: Near the end of the movie where H&K are stealing the skateboarder's truck, there is a Shoppers Drug Mart in the background. Shoppers Drug Mart stores are only located in Canada, not New Jersey.
Factual error: On the map, Budapest is indicated to be just as large as Transylvania, or at least of the same size category. Apart from Budapest being only a city and Transylvania a pretty large county, Budapest (taking its 19th century size) is not more than 500 square kilometres while the Transylvanian region is circa 57000 square kilometres.
