1. The idea to adapt Victor Hugo's Notre Dame de Paris came from the directors, Gary Trousdale and Kirk Wise, who loved the original story.
2. The gargoyles that are Quasimodo's friends are named Victor, Hugo and Laverne. Victor and Hugo were named after the author of the novel and Laverne was named after Laverne Andrews, a very successful singer. Originally she was going to be named Marie, as it was Victor Hugo's middle name.
3. Every scenario in the Notre Dame is real. The animators spent weeks around the cathdreal. Some people thought a gargoyle in Notre Dame was Pumba, making it an Easter Egg but it's a real gargoyle that you can see if you go there.
4. The first song of the movie ''Bells of Notre Dame'' was just narration, but it was dull to just listen to Clopin, the storyteller, and so it became a song.
5. Frollo, the villan, is the archdeacon in the novel, but it would cause too much religious contraversy so he became a judge. He still had a lot of power and influence, his attemps to destroy the Rromani (The Gypsies. But Rromani is the correct name to use, because Gypsy is a racial slur) wouldn't be questioned. The archdeacon in this film ended up as a mediator figure in the movie.
6. ''Helfire'', one of the darkest Disney songs ever written, was almost cut from the film.
It stayed, and works as a contrast with ''Heaven's Light''. Both are distorted love confessions as Quasimodo thought of Esmeralda as perfect angel instead of a person and Frollo thought of her as something demoniac to posess.
7. While Frollo is trying to say it's not his fault that his infatuated with Esmeralda, the chorus sings ''Mea culpa, mea maxima culpa'' which is roughtly translated from latin to: ''My fault, all my fault''.
8. When the animation for ''Helfire'' got through an editor, they thought Esmeralda on the fire seemed nude and made her clothes more defined.
9. In a scene from ''Out There'' you can catch two cameos. Belle from Beauty and the Beast and the Carpet from Aladdin!
10. The Hunchback of Notre Dame is the first Disney movie to almost say a curse word (the second is Moana) When Phoebus and Esmeralda meet, she almost calls him a sneaky son of b*tch but he interrupts her by saying they are in a church.
11. Red is a colour that represents evil throughout the movie. After Frollo completly loses his grip, he's very associated with the colour and the only time Esmeralda wears red is when Frollo sees her for the first time, making her also look evil, for a moment.
12. Frollo has an incredible dark aura. The other charaters seem smaller and impotent in his presence and the scenario goes darker.
13. If you notice, the villan's hat works as a mask (some fans call it the Sanity Cap). When it's on his head, he is composed and professional but when it's off, we see who he really is. A mad man that urgently needs a restraining order and counseling.
14. The directors confirmed that even if the gargoyles helped in the final battle, they are just Quasimodo's imagination.
15. Frollo's black horse is called Snowball! Yes, that pitch black horse in the image above is called Snowball.
16. There is a reference to a war, which Phoebus came back from. It's the ''Hundred Years War'' that happend in Europe from 1337 to 1453. France won.
17. The original plan was for Quasimodo to die in the ending, like in the novel. Frollo would sucessed in trying to stab him and and in the end, Phoebus and Esmeralda would ring the bells, as final wish from Quasimodo.
Thankfully for us, this happend
And if you've seen the movie, you know what this is.
