Corrected entry: After the expedition first meets the king, he says to Kida that 'a thousand years ago you would've killed them on sight', but then a few scenes later, Milo calculates that Kida must be only 100 years old.
Corrected entry: In the scene where Milo is explaining all the things that had to be done and put in storage for him to be able to attend the expedition, he finishes by asking, "My cat?" At that point his two year old Persian cat named Fluffy jumps onto his shoulder and he takes the cat in his hands. The next shot that we see of Milo his hands are on the desk and the cat is nowhere in sight, if he had time to toss the cat to the ground, we probably would have heard a little bit of a protest from Fluffy that his/her (I'm not sure which) owner had tossed him indignantly to the ground and had only paid attention to the animal for a few seconds.
Corrected entry: The Leviathan blew up the main submarine, and all that was left were two small missiles. But the characters end up having an amazing amount of equipment from that small space - three trucks, a metal crate, tents for everyone, and a huge blimp, to name a few.
Corrected entry: In the scene in which Milo is trying to get the fish vehicle started for Kida, Milo starts reading the inscription on the vehicle, from left to right, moving his finger along. But "Atlantean" for the movie was designed in the "boustrophedon" style (written in a horizontal line, running alternately from right to left and left to right). So the logical way to start reading the inscription, would have been to put his finger on the right side and start reading from there. (00:57:00)
Corrected entry: Several times during the movie, it is obvious that the clothing worn by Milo and a few others has zippers included by the sound effect that is heard. Yet, if the movie does take place in 1914, that isn't possible since zippers were not used in clothing worn by the common public until the 1920's.
Corrected entry: Mr. Whitmore tells Milo the crew that is to go in search of Atlantis is the original crew that went in search of the Shepherd's Journal. However, when the crew are all talking at bed time (when they invite Milo to join them), Audrey says she had never met Milo's grandfather. In Mr. Whitmore's photograph, Milo's grandfather is standing at the back of the photograph.
Corrected entry: When Milo refers to the "missing page" in the Sheperd's Journal, he looks at the right side of the book, then flips the page to look at the left. There is no space for a missing page.
Corrected entry: When Milo is vomiting over the boat he loses his glasses but when they go back to him he has his glasses back.
Corrected entry: Why is it that all of Rourke's troops wear an air mask, yet the air in Atlantis is obviously quite breathable?
Corrected entry: Early in the movie, a tank containing coelacanths is shown in Whitmore's office. However, the movie is set in 1914, and at that time no living coelacanths had been discovered. A single specimen was found in 1938, and another in the 1950s. Only recently have living coeleacanths been observed in their own deep-sea habitats.
Corrected entry: In the beginning, when the giant crystal is sinking the city, Kida drops her doll. When she goes to get it, her mum pulls her back, kneels down and tells her that "There is not enough time". It would have been faster to just get the doll, but the mum wastes ten times the amount of time to tell her not to.
Corrected entry: In the beginning Michael J. Fox's character tells us how the phrase "Coast of Iceland" was misinterpreted by others as "Coast of Ireland." He shows this with the phrase in both English and Altantian on a blackboard. But if they mistook the C's for R's, the phrase would have been as "Roast of Ireland."
