Cameos
An early form of the character of Jack Skellington from The Nightmare Before Christmas can be seen in the upper-left corner of the screen from 1:18-1:25 as well as in front of the embodiment of his deceased wife from 4:45-4:47. Jack also appeared in Tim Burton's Beetlejuice and the stop-motion animation film James and the Giant Peach. The first two cameos were years before production of Nightmare, though Burton had toyed with the original story idea while still an animator at Disney.
