Writer Tab Murphy was brought on board to write the screenplay, and it was decided early on that Quasimodo would be the center of the story, as he was in preceding live-action film adaptations.[13] A love story between Quasimodo and Esmeralda was originally conceived, according to Murphy, but "we decided to make Phoebus more heroic and central to the story. Out of that decision grew the idea of some sort of a triangle between Quasimodo, Esmeralda and Phoebus."[14] Some of the novel's key characters were jettisoned entirely while the gargoyles of Notre Dame were added to the story by Trousdale and Wise, and portrayed as comedic friends and confidantes of Quasimodo as implied in the novel, which reads "The other statues, the ones of monsters and demons, felt no hatred for Quasimodo…The saints were his friends and blessed him the monsters were his friends, and protected him. Thus he would pour out his heart at length to them."[15][16]
