Factual error: The strong current of the river the main character falls into carries him to a considerable waterfall. There is not, nor has there ever been, a river of that kind in the Ecoust front line area, let alone a waterfall. Anyone who has any insight into the geography of the region will tell you it is flat as can be. The largest body of water, the Yzer, gently meanders and flows into the Channel, even during really rainy times.
Suggested correction: I do not believe that either Ecoust or Croisilles Wood is in Flanders. Both are behind the old German lines at the Somme. That said, there are no bodies of water in that area.
Ecoust and Croissilles are in department Pas-De-Calais in the French Flanders, together with the Belgian flanders they are called Flanders Fields. It is indeed a flat area.
Also, the message in ink delivered is legible, despite having been submerged in water. And don't get me started about the attack from ridiculous trenches and not a barbed wire in sight.
It's not. Even French Flanders is further north. But, even though there are some high points in the area, like Vimy Ridge that rises to about 500 feet above the surrounding plains, the slopes are quite gentle. And, as you say, wouldn't allow for the kind of drop seen in the movie.
There is a watercourse that goes through Croisilles... But it's basically a ditch.
Visible crew/equipment: When Lionel returns to the jazz bar and discovers Billy Rose has been killed (framed as a suicide), you can see two people standing in the shadows to the left of Lionel as he enters the main room where the stage is located. A man is hunched over, whilst a woman is standing still wearing what looks like a dust mask. (01:32:27)
Factual error: No British woman measures her weight in pounds only - always stones and pounds, or kilograms (a concession to the Americans but it sounds really odd to us Brits). Yes, in the American printing of the book it's always only pounds as well, but that's for the same reason, and still wrong.
Continuity mistake: In the exterior front shots of Elliott's house there are some significant changes to the landscape in different shots. For instance, the two lampposts at the bottom of the driveway change to an entirely different style in some shots, and the huge garden boulders repeatedly vanish and reappear. Also, note when Michael takes off on Elliott's bike to go search for ET, the in-ground lamppost that should be beside the mailbox has vanished, but it reappears when all the government agents are setting things up outside the house.
Factual error: It is not possible to be "allergic to all known anaesthetics". Amongst the amide local anesthetics lidocaine, prilocaine, bupivicaine, mepivacaine and dibucaine are naturally occurring substances and if administered without a preservative they cannot trigger an allergic reaction. If Bales is allergic to them, he'd be allergic to the metabolic processes of his own body. They are all powerful local anaesthetics and could easily be used for a radical rhinoplasty such as that required by Bales.
Continuity mistake: During one scene in Camryn's Halloween birthday party (where she is wearing a silver mask), it is actually Tia playing this role instead of Tamera.
Revealing mistake: In the swimming pool scene, when David is sitting at the bottom of the pool, you can clearly see a scab on one of his knees. (00:43:00)
Continuity mistake: Right before they rob the police car, a Boeing 747 (four engines) is seen in shots of the plane coming into land. When the plane is shown from behind, it is a Boeing 767, with only two engines and fewer main landing gears. (00:30:10)
Suggested correction: It's for effect to show they were hanging out around the airport for more than a bit.
There's no evidence this was meant to be a montage scene of various planes. The cuts they did have in the first angle were of the same plane getting closer to build suspense. Same for the other angle. Plus, there's no scenes or shots of "them" waiting.
Revealing mistake: Near the end when Ace gets into his Cadillac, in the first shot facing the front of the car, there is a protective glass in front of Ace (the same width as the windshield) with the dashboard in between that glass and the windshield. Note the vertical edge of the glass is visible at the right side, and the rearview mirror's sticker on the windshield casts a shadow onto the second glass. During the stunt, the flames on the dashboard are between the glass shield and the windshield, keeping the actor safe from harm. (02:46:05)
Factual error: Before arriving at Brod station the train goes through high mountains. Between Belgrade (Serbia) and Brod (Bosnia and Croatia) it is all flat with no mountains around.
Factual error: Basic physics - Hancock throws Michel from a dead stop to above cloud level in about eleven seconds. The clouds are bog standard cumulus which form at around 7,000 metres in temperate zones. This means that Michel accelerates to about 700 metres per second instantly, from a dead stop. Obviously he cannot accelerate during his ascent, so his starting speed has to be at least that. (In fact he would have to start his ascent much, much faster than 700 metres per second as he would be constantly decelerating due to gravity and air resistance, but it will do as a start point.) Michel accelerates from 0 to 2,520 kilometres per hour - twice the speed of sound - in zero seconds. He would be accelerating at around 5000 Gs, turning him into a very long streak of fine, pink mist.
Deliberate mistake: The Messerschmitts have painted yellow fronts, this wasn't done by the Germans until after Dunkirk. Christopher Nolan has admitted doing this deliberately so the audience could tell the difference between the Spitfire and the Messerschmitt during the combat scenes.
Factual error: When Chigurh is in the gas station and throws the wrapper on the counter, the "Nutrition Facts" are visible on the label. Set in 1980, the "Nutrition Facts" label wouldn't have been available for at least another fourteen years, as nutrition labels were started in 1994.
Continuity mistake: Wardaddy raises his cigarette lighter to his cigarette twice while he speaks to Norman after the town has been taken. (00:51:30)
Revealing mistake: When Carl is being dragged away by the demons, you can see the cable line that he's attached to. May be fixed on DVD.
Audio problem: (May only apply to the original VHS release.) When Scar has Zazu locked up in a cage, Zazu mentions Mufasa's name and Scar yells at him, "What did you say?" Right before Scar's actual line, whilst Zazu is talking, you hear Scar's "What did you say?" line very faintly in the background, even though Zazu has not even mentioned Mufasa yet.
Plot hole: The huge guns are set high up on a cliff face facing out to sea and it is obvious that they cannot be depressed to fire at a downward angle - the massive gun carriages set on rails would prevent that happening. They cannot be elevated to fire at an upward angle, too, because they fit pretty snugly in the hole cut into the cliff face to accommodate them. This means that their maximum and minimum ranges would be quite close together, covering a strip of maybe a few hundred metres either side. Given that the sea is completely open on the side of the island they are protecting, why don't the ships targeted by the guns while passing the island simply sail inside or outside of the narrow stretch of sea the guns can hit?
Suggested correction: The guns are firing across a strait. A strait is a "narrow passage." Since the targets must appear at a limited range, the guns only need a limited elevation angle.
Watch the film again. The guns are facing the open sea. There is no land visible anywhere behind the ships. If that's a strait, it's a very, very wide one.
Other summaries explain that the strait is only deep enough for the ships at the place which matches the guns' range. So ships could not take advantage of further away or closer in.
Suggested correction: That the gun carriages are supposedly set on rails is not correct. In the novel template, as well as in the film, it is shown that the guns were installed on turntables. And as for their variable angles of fire - it could be due to (fictional) modifications.
Other mistake: When Adam comes in and says "when I woke up this morning, the pain was gone", Connie is mouthing his lines behind him.
Continuity mistake: Towards the end of the movie, when Joey Nova is trying to get out of town, he sells his football ring to the drug dealer, but in the final scene he is clearly shown wearing the ring when he points the gun at his father.
Continuity mistake: During his conversation with the director, while discussing his costuming, Dalton's hair changes from messy and curled to gelled up and straight.
