There has been some talk on the internet lately on whether The Nightmare Before Christmas is a Halloween movie or a Christmas movie. I say, why not both? The 1993 stop-motion film captured the imagination of children and adults alike, so there's no reason to limit it to just one holiday.

4. Tim Burton didn’t get to direct this movie.
He was busy on Batman Forever and Ed Wood so he had to have Henry Selick take over. Apparently he and Burton didn’t see eye to eye on a lot of things.
3. It was thought to be too dark for Disney.
This is why the film wasn’t released as a Disney film right away but was instead placed on the Touchstone Pictures banner. It was eventually brought back to Disney in 2006.
