Deliberate mistake: Obviously due to the family nature of the film, but when Peter stabs the White Witch's henchmen at battle, the sword always remains clean, and never bloody. (This is a Disney family film and as such no blood is shown. Still a mistake, but there's the reason). (01:56:10)
Deliberate mistake: Mr. Medulla said that Will stepped on his foot when he was walking to his desk. If you look closely you can notice that he stepped over his foot instead of on it.
Deliberate mistake: Charlie's room has a hole big enough for him to climb out of in the ceiling. I know it is to show just how poor the family is, but we see he has only a thin wool blanket for warmth. He would have frozen to death in his sleep during winter by now.
Deliberate mistake: In the end of the NASCAR race, Tripp and Gordon get into a crash making Gordon spin, but he somehow is still able to come in second place even though every other racer was right on his back when he spun. He wouldn't have been able to regain that much speed in that short amount of time.
Deliberate mistake: In the opening credits, there is a newspaper article showing that Dirk Pitt has found the remains of Nungesser and Coli's L'Oiseau Blanc, a plane that disappeared attempting to cross the Atlantic in 1927 before Charles Lindbergh made it. The wreckage in the newspaper photo is totally wrong; it has a radial (round) engine and cowling and a three-bladed propeller. The real plane had an inline engine, square cowling and a two-bladed propeller.
Deliberate mistake: The tiny hot air balloon that Francesca released in the debate room would never be able to support Casanova's weight.
Deliberate mistake: As the horse named "Sir Trenton", who is supposed to be a stallion, is galloping away you can see that "he" is a female.
Deliberate mistake: The turn count for Lisa's stay in the Cryogenic Sleep Chamber is off. The card reads she should be there for 5 turns. 'Turn' can either represent a single move made by either Danny or Walter, or a complete game cycle where both Danny and Walter have made a move. If we count the turns by player, it comes to 8 and she's awake 2 turns too late as it should have happened at the start of 6th. If we count both players' moves together as a start of a turn, then she's awake 2 turns too early as its turn 4 and not turn 6. It seems obvious from showing us the shower suddenly start up that this is the correct point in the film they wanted her awake, so it's unlikely she was actually awake off-camera during the Astronaut's arrival and we just didn't see.
Deliberate mistake: On the map showing the location of all the 'Camel Hump' refuelling blimps, none of them are anywhere near the countries EDI visits in the film - the nearest one is more than a thousand miles away over the Pacific.
Deliberate mistake: When the tribe does the ceremonial dance to bring the crow back to life, you can see the same shot of the bird leaping up twice.
Deliberate mistake: When Aeon is fastening ropes to lower herself down into the security system, her hair parting has switched sides as she fastens the second rope, revealing a flipped shot. (00:08:25)
Deliberate mistake: In the beginning of the film, the horse-drawn carriage driven by McGivens is able to crash through a brick pillar and keep moving forward... yet just one minute later in the scene, it's flipped and destroyed by a rope attached to a flimsy wooden spool. There's no consistency to the strength of the carriage.
Deliberate mistake: It's a really fun visual, but when the bad guys enter the kitchen and get swarmed by African-American waiters in white tuxedos, one can't help but wonder how it could be that Darius was almost the only waiter on the floor up until a moment before - there were a couple others, mostly white dudes, while now we see about 20 people, all of color, coming out at once. The disproportion is huge, it's not like dinner is being served. (00:39:30)
