Night at the Museum: Escape from the Smithsonian is now in theaters! Get this exclusive sneak peek now available on iTunes! It's a new "Night" and "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. Owen Wilson is back as cowboy Jedediah, and Robin Williams again rides into history as Teddy Roosevelt. The centerpiece of the film will be bringing to life the Smithsonian. No major film has ever shot inside the Smithsonian in Washington…until Night at the Museum: Battle of the Smithsonian.
