The top mistakes in Night at the Museum: Battle of the Smithsonian http://www.moviemistakes.com/film8018 en Sat, 21 Nov 2009 06:55:39 +0000 149509 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. 149300 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. 149316 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. 149654 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. 149305 Amelia Earhart's lipstick goes from on, to worn off, to on again throughout the movie.
