If the sequel to Night at the Museum wanted to retain the level of accuracy seen with the original, it would have a Chinese actor playing Russian Czar Ivan IV (aka Ivan the Terrible). But while I'm sure there will still be historical errors abound in Night at the Museum: Battle of the Smithsonian, the honor of playing Ivan has gone instead to pale-enough actor/filmmaker Christopher Guest (Best in Show), according to the Hollywood Reporter. And since Guest is actually a far more serious man than you'd expect, despite all those silly mockumentaries he writes and directs, here's hoping he studies his Eisenstein for inspiration.

A bunch of other actors have also joined Ben Stiller in the fantasy film, including Jon Bernthal (World Trade Center) as Al Capone, Bill Hader (Superbad) as General Custer, Alain Chabat (The Science of Sleep) as Napoleon and the franchise's screenwriters, Robert Ben Garant and Thomas Lennon, as the Wright brothers. This makes for a very packed cast, considering most of the first movie's co-stars are apparently returning, including Robin Williams, Steve Coogan, Owen Wilson, Ricky Gervais, Dick Van Dyke, Jake Cherry and Patrick Gallagher, the guy who looked all wrong for the part of Atilla the Hun. Other newbies to the series include Amy Adams as Amelia Earhart and Hank Azaria as Egyptian pharaoh Kah Mun Rah.

The sequel is currently filming in Vancouver, which seems a bit far away from the actual Smithsonian Institute, but reportedly the production will have access to shoot a few scenes in the actual museum, which is located in Washington, D.C. Maybe it will actually look like it takes place there, too.
