Factual error: The child Lily grabs an apple from a tree, the tree is an oak. Oak trees don't fruit apples.
Factual error: At the beginning of the film, after Eris gives her speech, we zoom in on a map of the Eastern Mediterranean - and the island of Cyprus is conspicuously missing (it's large enough to be seen on the map).
Factual error: When the train is travelling away from Paddington Station, the locomotive does not have a number on the buffer beam, but has a number plate on the smokebox door. It also has a large 'British Railways' symbol on the tender. In 1940, the Great Western Railway would have had the number on the buffer beam and a either a small GWR logo on the tender or Great Western in full. British Railways wasn't created until 1948.
Factual error: When we first see Kurgan in modern day New York, he begins to assemble his sword in a motel room. The very fact that he is assembling his sword the way he is, snapping segments together, especially the blade itself, which is segmented in the middle, would make that quite possibly one of the weakest and most inefficient weapons a person could ever wield. Being that it is segmented the way it is, it is structurally weak, and a clash against another sword, or any hard surface for that matter, would break the segments apart easily.
Factual error: There's a scene where Belle's father is riding away in the snow on his horse - the tracks left behind by the horse are exactly backwards. The round part of a horseshoe is at the front, not the back. (This was a deliberate 'in joke' done by the animators.)
Suggested correction: It is Belle who rides the horse in the snow, not Maurice. If we're talking about this being a mistake, then it could be a deliberate mistake, but if this was truly done as an in-joke, then I think it falls more under trivia. The tracks being backwards is factually incorrect, but it doesn't really fall under the category of "mistake" if it was deliberately done as a joke.
Factual error: Luc Crash holds the match unreasonably close to the gas-soaked priest, whom he intends to play with and not actually burn alive. At the distance he held the match, the fumes from the gas would have caught fire.
Factual error: In the birthday party scene Sebastian gets thrown into the air and lands in the birthday cake. A couple of shots later we see that the cake is completely obliterated. There is no way a crab Sebastian's size could create that much damage to such a large cake.
Suggested correction: This is an example of cartoon physics that isn't supposed to reflect reality.
Factual error: When Sally is leaving to rescue Gilly from her boyfriend she asks the Aunts to look after her children. The Aunts then say that they will take the children with them to the solstice celebration. A few days later when the cop is interviewing Sally he gives the date as March 8th. There are two solstices each year, one in December and one in June. Since this film takes place in early March, the Aunts could not have been going to a solstice celebration.
Factual error: Gollum's body wouldn't sink into the lava if he fell in it as shown in the movie. Rather his body would burst into flames, and turn to ash. Falling in lava isn't like falling into a lake. Lava is more than three times denser than water, which prevents a human shaped body from sinking in.
Factual error: When Young Hercules makes the pillars fall in a Domino effect, they go both ways. However, if this were to happen, they would stop the domino effect when they reach the entrance to the market, which doesn't have pillars. The pillars are not in a circle, so there's no way they can both stop at the top of the ring, where the pot seller is. The only way for this to work is if Hercules started the Domino effect at the entrance of the market, with pillars directly across from each other, which he doesn't.
Suggested correction: He throws the pillar he holds towards the opposite side causing it to fall as well.
They do a pulled back shot that shows it falling from the top of the ring.
Factual error: In the final scene, (19 years later) the aerial shot of Kings Cross station is actually St. Pancras station, which is across the road from Kings Cross.
Factual error: When the soldiers are asked to find out what gifts Andy is getting at his birthday party, the set out down stairs with half of a baby monitor. Well, any parent who owns one knows that there are 2 pieces to a baby monitor. One half (the larger half) is the receiving end (that takes in the noises) and a smaller half which is the transmitting part (the half that sends out the noises). The half that the soldiers take downstairs to talk through is the wrong half. They take the half that the noise comes OUT of. So, really, they should NOT be able to speak into this part - in real life, they'd hear what was happening up in Andy's room. (00:09:18)
Factual error: When Chitty Chitty Bang Bang arrives at the Potts' house, Grandpa Potts is sitting in a deckchair reading a very modern colour edition of National Geographic magazine.
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. (01:11:40)
Factual error: When the Security Guard in the pump room gets bitten on the nose, he starts shooting with his revolver (a SIX shooter). Count the bangs. He manages to fire SEVEN times. (00:39:45)
Factual error: In the bowling alley scene, Jack's friend tells him that Kate is well-liked in all of Union County, but in the movie, Jack and Kate live in Teaneck, which is in Bergen County.
Factual error: In the last scene of the chess game, you can see that both the Knight and Death have castled. Castling was introduced to the game of chess in the 16th century, well after the film is set.
Factual error: The French Cuirassiers are all carrying lances. Cuirassiers did not carry lances - their primary weapon was the sword.
Factual error: When Elliot is the sensitive guy he picks up the guitar to sing a song to Allison. The guitar has a capo on it. During the song Elliot is changing cords and finger placement. He makes a cord above the capo. This would not be possible since the capo effectively cuts off the strings at the point of the capo. Any finger movement above the capo would not change the chord at all. (00:43:00)
Factual error: Paris was surrounded by the German army on September 20th 1870, until January 1871 due to the aftermath of the Franco-Prussian War. This was an obvious danger after the defeat of the French army on September 2nd. No-one in Paris, however, seems to notice. (01:10:25)
