2. Patrick Stewart did the original introduction for the movie, which can be heard on the film's soundtrack.
3. Tim Burton has said the original poem was inspired after seeing Halloween merchandise display in a store being taken down and replaced by a Christmas display. The juxtaposition of ghouls and goblins with Santa and his reindeer sparked his imagination.
4. The teaser trailer tells us that the film was originally intended to by released under the Walt Disney Pictures banner, playing the movie heavily as the next generation of filmmaking following in the proud tradition of Walt Disney. By the time the theatrical trailer was released, the release label had changed to Touchstone Pictures, an alternate designation of the Walt Disney Studios. Michael Eisner, the then CEO and Chairman of The Walt Disney Company, found the film to be 'too dark for kids' and had it moved to their Touchstone Picture banner. In October 2006, the film was re-released in 3-D under the Walt Disney Pictures banner.
5. Tim Burton had hoped to direct, but placed Henry Selick in the director's chair instead as Burton was busy working on Batman Returns (1992).
6. In the original poem written by Tim Burton, the only characters that existed were Jack, Zero and Santa. All the other characters were made up for the movies, although he describes some of the presents which were given out, including in some cases the names of the children.
7. Danny Elfman did the singing voice for Jack because Chris Sarandon said he did not have a good singing voice.

11. It is stated in "The Making of..." book that the most difficult shot to film in the entire movie is the shot in which Jack is reaching for the doorknob to Christmasland. Viewers can see the perfect surround reflection of the forest around Jack in the background.
12. Tim Burton wrote a three-page poem titled The Nightmare Before Christmas when he was a Disney animator in the early-1980s. Burton took inspiration from television specials of Rudolph, the Red-Nosed Reindeer (1964), How the Grinch Stole Christmas! (1966) and the poem A Visit from St. Nicholas. On the 2008 Special Edition Blu-ray/DVD release, Christopher Lee narrates this poem with a new animated visual accompaniment.
13. In 2001, Walt Disney Pictures began to consider producing a sequel, but rather than using stop motion, Disney wanted to use computer animation. Tim Burton convinced Disney to drop the idea. "I was always very protective of [Nightmare] not to do sequels or things of that kind," Burton explained. "You know, 'Jack visits Thanksgiving world' or other kinds of things just because I felt the movie had a purity to it and the people that like it," Burton said.
