Night at the Museum: Battle of the Smithsonian (2009) - 26 mistakes

Visible crew/equipment: In the scene with Darth Vader and Oscar the Grouch, watch Darth Vader's eyes. You can see the light screens and crew reflected in his eyes in every shot.

Continuity: When Kahmunrah first appears on Archie Bunker's chair, the propeller beanie cap hanging on the side of the chair disappears in the close-up.

Factual error: 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.

Factual error: When Larry and Amelia run inside to the Air and Space museum to find the Einsteins, you can see on the wall "Air and Space Museum." There is no lettering on the outside of the museum indicating its name.

Continuity: Amelia Earhart's lipstick goes from on, to worn off, to on again throughout the movie.

Continuity: When Octavius and Jedediah escape through the hole in the metal container in the close-up, the shape of the hole changes in following shots.

Continuity: In the opening sequence Sacajawea is placed in a crate of tan, straw-like packing material. When Larry visits the museum a few hours later, Sacajawea emerges from a crate full of white packing "peanuts" (styrofoam pellets).

Revealing: When Amelia and Larry are flying, his hair doesn't move a single inch.

Revealing: When Larry and Amelia's plane takes off, the cables it is held onto easily rip off from the canvas. For security measures, a real cable would be made of steel, therefore ripping the structure instead of just snapping like a string.

Continuity: 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: 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: 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: When the cowboy and the Roman are standing on the crate, from behind you can see that the Roman's cape is long and covers part of the edge of the crate, but from the front is shorter and doesn't even touch the wood.

Continuity: 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: During the glowing torch commercial, the actor opens a drawer with metal stuff in, but in the wide angle a wooden stick appears.

Continuity: 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: When Larry's chauffeur takes him to the museum, the car passes way after a blue lamppost, but in the close-up it parks right next to it.

Continuity: 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: 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: While Custer is guessing the Indian woman's name the monkey behind her appears and disappears.
