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.
