Arthur Christmas is a 2011 3D computer-animated fantasy film and was the first Sony Pictures Animation film co-produced with Aardman Animations. The film is based on the premise that Santa Claus is not a person but actually a hereditary title carried on by different individuals over generations. Set on Christmas night, it tells a story about Arthur Claus, the clumsy but goodhearted son of the current Santa, who discovers that Santa's high-tech ship has failed to deliver one girl's present. In response, he embarks on a mission to save her Christmas, accompanied only by his free-spirited and reckless grandfather, a rebellious yet enthusiastic young Christmas elf obsessed with wrapping gifts for children, and a team of eight strong, magical yet untrained reindeer.
