Arthur Christmas is a 2011 animated movie that's already become a bit of a Christmas classic for many.

With a voice cast that includes James McAvoy, Hugh Laurie, Bill Nighy, Jim Broadbent, Imelda Staunton and Ashley Jenson, it follows Santa Claus's clumsy son Arthur as he goes on a mission to save one little girl's Christmas after her present isn't delivered.
