Swanberg's 'Happy Christmas' found success even before the festival began. Magnolia and Paramount Pictures partnered to release the film and the cast was celebratory on the carpet. At the Sunday premiere, ATW got to chat again with Swanberg and talk how he used his own life to create the story of the film.  His precious son Jude steals the show alongside Anna Kendrick, Lena Dunham, Mark Webber and Melanie Lynskey.
