A second teaser trailer for Sony and Aardman’s upcoming animated comedy Arthur Christmas has just been revealed over at Yahoo! Movies. As was the case with the first preview, it uses a “shaky camera” effect to show Santa’s son Arthur showing us top secret things about his father’s business. Starring James McAvoy as Arthur and Jim Broadbent as Santa Claus, Arthur Christmas is facing pretty fierce competition for the family market this holiday season, including The Muppets, Happy Feet Two and Hugo, Martin Scorsese’s first ever 3-D movie.
