Christopher Guest has just signed on to an already loaded cast for Fox’s upcoming sequel to A Night at the Museum.

Ben Stiller, Robin Williams, Owen Wilson and Ricky Gervais are all returning for the franchise’s second installment, joining Jon Bernthal (as Al Capone), Bill Hader (as Gen. Custer), French actor Alain Chabat (as Napoleon) and Guest himself, who’ll play Ivan the Terrible.

The biggest star of all though, might just be the backdrop, as certain scenes will be filmed inside Washington’s Smithsonian Institute, a privilege rarely granted.

Director Shawn Levy will reunite with original Museum writers Robert Ben Garant and Thomas Lennon for the new film, A Night at the Museum: Battle of the Smithsonian.

The first Museum raked in $574 million for Fox and with its beefed up cast and location, the sequel looks like it could earn even more.
