Corrected entry: There is no way Amelia Earhart could have flown them back to NY by flying out of the National Mall and landing in the middle of NYC. Those two areas are two of the most controlled air spaces in the USA. Fighters would've been scrambled before they got 10 minutes into the air.
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.
Correction: Kahmunrah is an idiot so he wouldn't have known that. Jedidiah is just playing along with 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: Towards the end Larry gets the octopus into the reflecting pool, when the octopus first jumps in (which is a problem by itself) it is completely submerged. But the reflecting pool is only about 18 inches deep. So there is NO WAY that this octopus would be able to do this.
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.
Correction: This isn't a mistake. The filmmakers simply chose not to show Larry and Amelia running in the dark between the locations. There really isn't any implied suggestion that these landmarks are adjacent.
Corrected entry: We can see them flying around the museum with the right brothers plane. However that plane could only fly a few feet and not such a long way.
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.
Correction: It's about 200 miles from DC to New York, a small plane with a good tailwind could do it in well under an hour (remember, Larry says it's "about" an hour... he could be off by several minutes or even exagerating a bit to get people moving faster). The plane lands at the museum, there is no travel time from the airport. As for the loss of time because they are flying east, New York is northeast of Washington DC, not due east. They are only going about 120 miles east of their origin. The circumference of the earth at Washington's latitude is just over 19,000 miles; if they flew 120 miles east they would only lose 9 minutes of darkness.
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?
Correction: As seen in the first film a number of the exhibits left the museum and were wandering around Manhattan. It seems that the tablet's magic brings them back for an entire night until sunrise, regardless if they are near the tablet or not.
Corrected entry: When Amelia Earhart lands her plane in front of the Museum - on Fifth Avenue, there is a double yellow line right down the middle of the street, but Fifth Avenue is a one way street.
Correction: The American Museum of Natural History in New York City is not on Fifth Avenue but on Central Park West, and Central Park West is a two-way street.
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.
Correction: It does not look like they all could have fit into the plane, but that is an opinion, not a movie mistake. It is also an opinion to say that the plane could not take off bearing the weight of everyone on board. First, you don't have the specs on the plane and second, you don't know how much the "people" weigh. Remember, Larry is the only real person on the plane, the rest are wax figures - maybe even hollow wax - and most likely weigh only a fraction of their human counterparts.
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.
Correction: Just because they don't show everyone getting off the plane does not mean that they were not on it.
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.
Correction: When Joey Motorola is seen with the cellphone, it's a wink and a nod to the change in technology. It's not meant to be historically accurate. It's the filmmakers' prerogative.
Correction: Whether or not it be a nod to the creation of Motorola, even the name itself was shoehorned in, as Motorola got its name from the portmanteau of "Motorcar" and "Victrola", a popular radio model at the time.
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.
Correction: First, Egyptians didn't use 3.16 as pi - they had no concept of pi at all. Second, the Einstein bobblehead says "3.14159265, to be exact" referring to the combination needed to unlock Akmenrah's tablet, not pi itself, and the combination is an exact number.
Correction: The figures are approximations of the people they are based on, not duplicates. Teddy Roosevelt makes this clear in the first film when he says "Actually, I never did any of those things. Teddy Roosevelt did. I was manufactured in a mannequin factory in Poughkeepsie. I never shot a wild beast. I'm not even brave enough to tell that beautiful woman [Sacagawea] I love her. But you... you gotta finish the job this time. You can't quit. I'm made of wax, Larry. What are you made of?"
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.
Correction: Most major radar stations rely on "Secondary Radar" which requires the aircraft to carry a Radio Transponder which transmits the aircraft data to the requesting station, the Lockheed Vega Amelia is seen flying was first built in 1927 a full 23 years before the Radio Transponder was introduced into commercial aviation, the aircraft would not have been picked up on "Primary Radar" either as the aircraft is mainly made of wood whereas "Primary Radar" only works effectively with aircraft made mostly of metal.
