Continuity mistake: Roosevelt enters the scene and Larry greets him. The Indian woman's arms change from being crossed to down and next to the hips between shots.
Continuity mistake: When Larry first starts playing with Rex there is a sheet under Rex by his feet which is folded up neatly, but two seconds later the sheet is now disheveled and partially on the floor. Then within seconds this sheet is now still disheveled but completely on the edge of the display. (00:10:00)
Continuity mistake: When Larry and Brundon are saying good-bye both times, their distances between each other keep changing great distances instantly.
Continuity mistake: Custer explains to the Indian girl and the primitives how to attack and there's a close-up of the monkey with his hand on his chin. A second later, a wider angle shows the hand resting on the side.
Continuity mistake: The way crates are placed differs enormously between the moment before and after the dinosaur throws Ben Stiller flying. Watch the crates on the back: First they are spread apart, perpendicular to the animal, but when Stiller lands they're parallel and close together to hide the safety crash mat in between.
Continuity mistake: Ben Stiller takes a rope out of a bag which he throws away. When the dinosaur sends him flying away the bag is nowhere to be seen.
Continuity mistake: When the cowboy is standing on the edge of the crate scolding Larry, the position of his arms has no continuity whatsoever between the front and back shots.
Continuity mistake: When Jedediah is in the hour glass, he is in the lower chamber, and the area between is too small for him to go through. When the minions are returning to the portal, in a close up he is obviously in the top chamber, only to return to the bottom when Octavius breaks him free.
Plot hole: Before Amelia Earhart flies herself and Larry back to NYC from Washington D.C. Larry says that there is an hour of darkness left. The time needed to fly from Washington D.C. To NYC and back is well over an hour, so it's not possible to make it in the time given and Amelia would have turned to dust.
Deliberate mistake: It is totally unlikely that a museum as careful and important as the Smithsonian would leave the crates un-nailed, which could make the pieces inside get damaged. Of course if the crates weren't open, none of the figures could come up to life.
Continuity mistake: Jedediah is trapped inside an hourglass, and at one point the sand is almost up to his neck, but in a later shot the sand is only up to his chest.
Continuity mistake: When Abe Lincoln picks up Larry the tablet is missing only to return after he sets him down.
Continuity mistake: When Larry opens the octopus on Kahmunrah's men, the tablet disappears from Kahmunrah's arm several times before it is knocked out of it by the octopus.
Continuity mistake: When Custer is explaining how they will yell "Attack!" before attacking and Sacajawea questions the veracity of this plan, she is first in front of the caveman, etc. (with her back to the door of the box-crate) and then with no one behind her (with her back to the side of the box-crate).
Other mistake: As Kahmunrah is entering the combination 3.14159265, the last two numbers that he is entering is 95, not 65.
Continuity mistake: When Custer slams his head, the sidecar is seen driving past several boxes, far away, but a couple shots later show it way behind, only a few meters from Custer.
Continuity mistake: When the Roman Emperor is talking while standing on the crate, the objects behind and the position of the styrofoam differs between the close and wide shots.
Continuity mistake: When Sacagawea wakes up from her shipping container, the styrofoam popcorn comes out everywhere as she gets up. But moments before when it shows her being put into the box, there is no styrofoam, rather she's packed in with hay.
Factual error: When Larry and Amelia enter the VJ day at Times Square photo (AKA kissing sailor) we get to see what was in front of the sailor and nurse but Alfred Eisenstaedt, the photographer who took the picture, is nowhere to be seen.
Continuity mistake: On his horse, Teddy Roosevelt greets Larry and extends his hand as Larry enters the scene and extends his. A quick cut to Teddy's point of view and Larry walks up and extends his hand again.
Answer: Yes. But he obviously doesn't think to do so.
