I remember seeing Disney's animated THE HUNCHBACK OF NOTRE DAME years ago and not being too impressed with it.
I did not know they had turned it into a stage musical. However, if they can make money with it "out-of-town," why not?
Years ago, I recall my clients, lyricist Paul Francis Webster and composer Sammy Fain, did something similar with a stage version of CALAMITY JANE, which had won them a "Best Song" Oscar for "Secret Love". When the show was adapted to the stage, they made a decision NOT to take the play to Broadway. They were doing great with it in regional and summer stock theaters and, according to Webster, if it had played New York and received bad reviews, that would have killed it.
Later, I believe, it was done as a television special with Carol Burnett.
