how did they make the nightmare before christmas

The movie was created by Henry Selick, who was inspired by the dark and surreal atmosphere of Halloween. He wanted to make a movie that would capture the spirit of Halloween and Christmas at the same time. The film features stop-motion animation, which is a time-consuming and labor-intensive process. It took a team of animators over two years to create the film's 2,275 shots. The movie was released in 1993 and has since become a classic holiday film.
