Corrected entry: It is established in the first movie that even when they come to life that they are still made out of the materials in which they were fashioned. Therefore, they have no internal organs, and Jedediah doesn't even need to breathe while in the hourglass. Suffocation wouldn't have killed him.
Corrected entry: Amelia saying that Larry 'couldn't take his cheaters of her chassis' - using the word cheaters to mean his eyes - is incorrect. The slang term 'cheaters' was a reference to glasses/ spectacles, because using them to help enhance vision was 'cheating'.
Corrected entry: The quick cuts between scenes in the Air and Space museum, the White House, and the Lincoln memorial imply that they are adjacent. However the White House is 1 mile away and the Lincoln Memorial is over 1.6 miles away.
Corrected entry: While at the Smithsonian, Larry notes it's about one hour until sunrise. A few minutes later, everyone going back to New York City piles into Amelia Earhart's airplane and she takes off. When they land, it's still dark in the sky above New York City. If it was an hour before sunrise, the sky would not be so dark and New York City is farther east than Washington, D.C., thus would get the sun a few minutes earlier. Also, modern airplanes barely can make the Washington to New York City trip in barely a hour. That isn't including travel time from the airport to the museum. Larry should have fallen out of the sky when everyone and everything around him turned to dust with the rising sun.
Corrected entry: After Amelia flies the characters to the museum from the Smithsonian, she hops back in the plane and flies off. How? If she's not with the tablet wouldn't she turn back into a wax figure?
Corrected entry: In the fight scene between Larry and Kahmunrah, Larry throws the tablet to Amelia Earhart. When the shot cuts to Amelia, you can see that two of the squares on the tablet are turned. In the first movie, the tablet didn't work when squares were turned, so none of the exhibits should be alive.
Corrected entry: When they shipped out the displays to the Smithsonian they needed to use an 18-wheeler tractor trailer. But on their return trip on Earhart's plane, the entire gang was able to fit onto the plane easily. Also, the sheer weight of all of them would've prevented the plane from rising off the ground.
Corrected entry: After Amelia flies Larry and the others back to the museum from the Smithsonian, several characters exit the plane. A couple of scenes later, Sacajawea (who was one of those taken to the Smithsonian) is back at the museum, although she didn't exit the plane.
Corrected entry: During the credits a kid named Joey Motorola is seen reverse engineering a cell phone from Larry's phone. Although one of the founding brothers of Motorola was named Joseph, their last name was Galvin, Motorola was the product name. Also, the Galvins were from Chicago, not New York as the film implies.
Corrected entry: When bobble head Einstein states the value of PI as 3.14159265, he says "exactly". Einstein would never have said anything like that, since PI is an irrational number that goes on without end. Furthermore, the best approximation for PI that the Egyptians had was 256/81 or about 3.16, so they certainly would not have set their code to 3.14159265.
Corrected entry: When Larry is walking away from Brundon, you can see Brundon in the distance and he is simply walking. When the camera cuts closer to him, he is playing around with the flashlight. When the camera cuts back to Larry with Brundon in the distance, Brundon is simply walking again.
