Arthur Christmas is a 2011 animated Christmas comedy film produced by Columbia Pictures, Sony Pictures Animation, and Aardman Features and distributed by Sony Pictures Releasing. The film is Aardman's second computer-animated feature film after 2006's Flushed Away. It was directed by Sarah Smith (in her feature directorial debut), co-directed by Barry Cook, written by Smith and Peter Baynham, and starring the voices of James McAvoy, Hugh Laurie, Bill Nighy, Jim Broadbent, Imelda Staunton, and Ashley Jensen. The film tells the story of Santa Claus' family as one of his sons works to deliver an overlooked bicycle to a little girl in Trelew, Cornwall, England before Christmas morning.

Following the under-performance of Flushed Away, DreamWorks Animation did not renew its partnership with Aardman. In April 2007, Aardman signed a three-year deal with Sony Pictures. Originally titled Operation Rudolph, the project was first announced in 2007. Aardman spent 18 months on pre-production on the story and design in the UK before relocating to Sony's animation studio in Culver City, California, for another 18 months of production. On 27 April 2009, it was reported that production had begun with Aardman and Sony Pictures Imageworks working together on animation.

Arthur Christmas was released on 11 November 2011 in the United Kingdom, and on 23 November in the United States. The film received positive reviews from critics, and was a sleeper hit earning $147 million at the box office.
