It's both a new 'night' and a new 'museum' for Ben Stiller, who is joined by several other stars from the original film, as well as new characters from history - including Amy Adams as famed aviatrix Amelia Earhart, Hank Azaria as villainous Egyptian pharaoh Kahmunrah, Christopher Guest as Russian tyrant Ivan the Terrible and Alain Chabat as Napoleon. Owen Wilson is back as cowboy Jedediah, and Robin Williams again rides into history as Teddy Roosevelt. The centerpiece of the film is that it brings to life the Smithsonian Institution. Housing the world's largest museum complex, the Smithsonian has a collection of more than 136 million items - ranging from the plane Amelia Earhart flew on her non-stop solo flight across the Atlantic to Al Capone's rap sheet and mug shot to Dorothy's ruby red slippers and Archie Bunker's lounge chair.

In this second installment in the Night at the Museum saga, Larry faces a battle so epic it could only unfold in the corridors of the world's largest museum. Now, Larry must try to save his formerly inanimate friends from what could be their last stand amid the wonders of the Smithsonian, all of which - from the famous paintings on the walls to the rocket ships in the halls - suddenly have a mind of their own.
