was nightmare before christmas claymation

That's right, the Nightmare Before Christmas was originally created in 1993 as a claymation film. Claymation, also known as stop-motion animation, involves creating models of characters and objects out of clay, and then moving them slightly between frames to create the illusion of movement. It's a very labor-intensive process, but it can also result in some truly amazing effects, as seen in the Nightmare Before Christmas.
