I saw the trailer for this when we took Buddy to see "Bolt" a while back but I never realized it was all stop motion. Now I want to see it even more. Actually I wish they'd make a full length documentary of how they made it, getting to see all the little props would be amazing. Here's a little bit of the process.
(Added: if you go to the website and click on Coraline's bedroom link there's a great little short film about Althea Crome the knitter of Coraline's teeny sweater as well a free pattern to make the sweater in child and adult sizes.)
