The Nightmare Before Christmas undertaken an extensive marketing campaign of these characters across many media. Since 2001, Disneyland has held a seasonal "Nightmare Before Christmas" theme for its Haunted Mansion Holiday attraction. The attraction, an overlay of the park's Haunted Mansion, features characters, decorations and music from the film. In addition to Mickey's Not-So-Scary Halloween Party and Mickey's Halloween Party featuring the film's characters, Jack Skellington, Sally, Pajama Jack, and the Mayor have been made into Bendies figures, while Jack and Sally even appear in fine art. Moreover, Sally has been made into an action figure and a Halloween costume. A Jack Skellington figurine
The Nightmare Before Christmas asked on Burton's involvement, Selick claimed, "I don't want to take away from Tim, but he was not in San Francisco when we made it. He came up five times over two years, and spent no more than eight or ten days in total." Walt Disney Feature Animation contributed with some use of second-layering traditional animation. Burton found production somewhat difficult because he was directing "Batman Returns" and in pre-production of "Ed Wood". The filmmakers constructed 227 puppets to represent the characters in the movie, with Jack Skellington having "around four hundred heads", allowing the expression of every possible emotion.
