1. The stop-motion musical had 24 frames to a second, meaning they had to pose characters 24 times for each second of the completed film.
They had to move a character, take a picture, move the character, take a picture, and so on.
4. And the movie therefore took more than three years to complete.
5. There are as many as 60 individual characters, with three or four duplicates each.
7. The sculpture department consisted of only four people.
And they did all those characters.
8. More than 400 distinctly different Jack Skellington heads were used.
9. And Sally had a mask for every expression change.
They couldn’t give her different heads because of her long red hair, which is why they created the masks.
10. To make Jack blink, replacement series were wedged into his eyes, which took up three frames per blink.
11. Set designer Gregg Olsson built a quarter-scale mock-up of Halloween Town as a model for the real set.
Parts of the set also broke off into smaller pieces because the real-size set wouldn’t all fit in one space.
12. The set also had trapdoors so animators could pop up and do the animation from beneath.
13. Although the sets were built in miniature, they were lit as if they were full-size movie sets.
They just used smaller lighting instruments.
14. Many of the sets required as many as 20-30 lights to create dramatic effects.
15. If there was ever a problem with a frame, they would have to go back and re-photograph the entire thing.
16. Composer and lyricist Danny Elfman didn’t have a script to write the songs from.
He asked Tim Burton to describe a scene and then Elfman would compose the song.
