In the new Aardman/Sony Pictures 3D CG film, "Arthur Christmas," it's revealed that Santa has two sons: the younger, Arthur, and the elder, Steve, who runs the elf labor camps with "military precision." A voice cast has already been found: James McAvoy will play Arthur, Hugh Laurie will voice the older brother and they are joined by Jim Broadbent, Imelda Staunton and Bill Nighy.
Presumably Nighy or Broadbent will voice Santa and our hope is its the latter. Sarah Smith and Barry Cook are co-directing, with the supremely busy Michael Giacchino and Adam Cohen composing the score. Sony have set the film for a November 23, 2011 release. [Bleeding Cool/Deadline]
