This movie is a Halloween/Christmas movie. I watch it every year. Gotta love Jack Skellington, who is a being from "Halloween Town," as he discovers a portal to "Christmas Town." Danny Elfman wrote the film score and and provided the singing voice of Jack as well as other minor characters. This was a 1993 film directed by Henry Selick and produced/co-written by Tim Burton.
