Mrsasta has a photo gallery of an exhibit of the Tim Burton puppets and concept art from The Corpse Bride. I hadn’t been drawn to see the movie until I saw these, but now I think I must.
Here also is an interview with Graham G. Maiden, the head of the puppet department on the Corpse Bride. And Stop Motion Works’ Corpse Bride page has a link showing the inside of a Corpse Bride puppet, and some on-set photos.
