I thought Aardman Animations had abandoned computer generated animation after Flushed Away (2006). Maybe Sony made them an offer they couldn't refuse. Their new film is Arthur Christmas (2011) in 3D. The bad news is that Sony Pictures Animation wrote the script, so it lacks the British humour of Wallace and Gromit as well as the stop-frame animation which Aardman does so brilliantly. Will it give us a Christmas giggle? Try the trailer. It doesn't look very promising. Click the title link for a BBC News video.
