Ben Stiller is in Washington this week filming exteriors for Night at the Museum 2: Escape From The Smithsonian.

This is the first production allowed to film in the famous national museums and, as such, includes more historical figures coming alive. Dick Van Dyke, Owen Wilson, Ricky Gervais, Robin Williams and Steve Coogan are expected to return with Amy Adams joining the cast as Amelia Earhart and Hank Azaria as a villainous Pharaoh.
