EXCLUSIVE: Tony-winning M. Butterfly playwright David Henry Hwang has been set by Disney to write Hunchback, a live-action musical adaptation of the Victor Hugo novel. Alan Menken and Stephen Schwartz will write the music. Mandeville is producing along with Josh Gad. I had heard that Gad, a star of the Mandeville-produced blockbuster Beauty and the Beast, might play the lead character, but insiders at the studio said no casting is solid at this point.
