I honestly think Nightmare Before Christmas would make an amazing show!
The sets could be awesome, the characters are endless, the songs are great, and the story is amazing. I've been a huge fan of this movie since it came out and I've always pictured a show being made from this movie.
The only thing that would have to be done is Jack would have to be an animatronic that moves around the stage. He couldn't be played by an actor or else it just wouldn't look right. He would have to stay skinny, tall, and move just like the actors. I honestly think this could be done with different sets and the stage set up in the right way. He could be controlled from underneath the stage and with the right lighting and choreography, it could work!
