Nightmare Fuel: The Hunchbackof Notre Dame
The Disney version:
The gargoyle that randomly comes to life just to finish off Frollo...
The statues of the saints looking down at Frollo, and of the Virgin Mother's eyes opening as the lightning flashes in the prologue.
Frollo looked positively demonic during the chase leading up to that scene, and it definitely didn't help that the guy killed Quasimodo's poor mother. And what's worse is that he thought he was guiltless!
Quasi being almost strangled and beaten as the "King of Fools".
Judge Claude Frollo himself.
Most of the other Disney villains were terrifying and evil in their own right, but Frollo trumps a majority of them as far as pure evilness goes, due to being very, very normal and realistic. It gets better. The chances of you personally getting attacked by a sea witch, a sorcerer, or an evil queen is slim to none. Are there genocidal racists out there who use religion to justify their beliefs, and convince other people to follow them? Oh, yes.
His obsession with Esmeralda is quite creepy indeed, and not at all subtle.
The scene where he confronts Esmeralda while she's about to be burned telling her to "Choose me or your pyre".
When he says "Let her taste the fires of hell," you can actually hear the faint screaming of a woman being burned alive! Chills.
Frollo looks very like The Joker when he grins, and his cold glare is equally as frightening.
Imagine for a moment you are one of the soldiers under Frollo's command. Specifically, one of those attacking the Cathedral. You've stuck by the Judge through all of his monstrosities. The city is in revolt, the Cathedral is throwing beams, stone and molten lead at you. All of this is explainable. Then the birds attack and everything is put into perspective. The Cathedral isn't attacking you. God is and now the Devil has a claim on your soul. Pious or not, that would be terrifying.
The last twenty-five seconds of "Paris Burning" is the embodiment of fear and terror itself. In the film, it's played over a clip looking over the skyline of Paris, glowing bright red from all the fire and the smoke filling the sky, as though Frollo really has brought Hellfire to Earth.
If you interpret the gargoyles strictly as part of Quasi's imagination, not to mention how he behaves around Frollo, it really puts into perspective how much psychological damage has been done to this poor boy in his 20 years in isolation.
