Animated seasonal family comedy featuring the voice talents of James McAvoy, Jim Broadbent and Hugh Laurie. Santa (Broadbent), along with his family and helpers, work hard every year to get presents out to everyone in the world on Christmas Eve. While people sleep soundly in their beds, they are unaware of the high-tech operation run at the North Pole that exists so that they can get their presents. Behind this slick and efficient machine however, are the disparate and dysfunctional members of Santa's family, including his cranky 136-year-old father Grandsanta (Bill Nighy), his devoted wife Mrs Santa (Imelda Staunton), and his poles-apart sons, Steve (Laurie) and Arthur (McAvoy). Can they all work together for the sake of Christmas?
