Arthur (James McAvoy) is one of Santa's two sons, a bungler with a big heart. He takes it on his own to bring a present to the one girl in all the land whose present was not delivered. His technocrat brother, Steve (Hugh Laurie), has been responsible for the mis-delivery, although his array of laptops for elves and computerized delivery system is impressive. The head versus the heart forms the central conflict, providing laughs and groans but never in a mean way as in Bad Santa.
