Tim Burton's Nightmare Before Christmas has become a beloved classic. One which can be enjoyed around Halloween or Christmas. The film, along with hits like Batman, Batman Returns and Edward Scissorhands cemented Tim Burton's status as an auteur.
There's just one problem: Tim Burton did not direct Nightmare Before Christmas. Henry Selick can lay claim to that honor. He also directed James and the Giant Peach as well as Coraline the latter of which Tim Burton had nothing to do with. It's interesting to note that Tim Burton has become a household name as a director thanks in large part to a film directed by a man whose name relatively fewer people are familiar with. I bet you had to look at the beginning of this paragraph to remind yourself of his name.
The poor guy has a smile that looks like it belongs to a wily, toothless 19th century prospector.
Here's another interesting fact about Nightmare Before Christmas: While Chris Sarandon (who incidentally, also played Prince Humperdink in Princess Bride) provided Jack with a speaking voice, it was the film's composer, Danny Elfman, who did all the singing for Jack. Elfaman would later sing again for a Tim Burton-Produced film when he provided the Oompa-Loompas with their singing voices. Just to give you an idea of how different Danny Elfman sounded in each, here are a couple videos.
