The very first trailer for Night at the Museum: Battle of the Smithsonian has arrived online ... via the McDonald's Happy Meals website. Not exactly ideal viewing (who knew McDonald's was fighting their way into the trailer premiere game), but if you want to watch the preview, head on over here.

There doesn't look to be anything groundbreaking here -- if you were a fan of the first film, you should dig this one quite a bit. In fact, this looks just like the first Night at the Museum, except, like any sequel, there are more characters, more special effects and more gags. Story once again follows our clumsy night watchman (Ben Stiller) who rushes to the Smithsonian in Washington D.C. after his friends Octavius (Steve Coogan) and Jedediah (Owen Wilson) are accidentally shipped there. Also starring in the film are Amy Adams, Bill Hader, Ricky Gervais, Hank Azaria, Eugene Levy, Christopher Guest and more. Night at the Museum: Battle of the Smithsonian hits theaters on May 22.
