NIGHT AT THE MUSEUM: Larry (Ben Stiller) accepts a job as a night guard at the Museum of Natural History, in an attempt to prove his stability to his ex-wife and his son Nicky. But the elderly night guards who hire him fail to mention one crucial detail: when the museum is closed, everything inside comes to life... ALVIN AND THE CHIPMUNKS: Finds the chipmunks transported from their woodland habitat to the city, where they wind up in the home of Dave Seville. Dave realises the potential of a singing chipmunk pop act and becomes an unlikely mentor/father figure to Alvin, Simon, and Theodore. When a devious record executive enters the picture, however, Alvin and the Chipmunks must deal with both the trappings of fame and their loyalty to the amiable, hapless Dave.
