Especially the last note that Paul Kandel (Clopin) hits FULL-VOICE.
If you look at the sheet music, it's a D on two ledger lines. Tenor parts are written an octave higher than they sound. Still, it is quite impressive.
This scene when the Archdeacon says the lines below, it was very much a 'Oh, you're gonna get yours when it's over!' and it felt wonderful.
Archdeacon: You can lie to yourself and your minions, you can claim that you haven't a qualm, but you never can run from nor hide what you've done from the eyes! The very eyes of Notre Dame!
Then the cathedral itself gets one with all the statues looking down at Frollo, as if God is saying "Yeah, throw that baby down the well, you son of a bitch, and see how pissed I get."
Considering by this point in the movie that Frollo has already condemned three people to torture and eventual death and killed an innocent woman on the steps of a cathedral, it's wise not to push The Man Upstairs any further. That was the first and only time in his life that Frollo ever considered the morality of his own actions.
The Archdeacon in general gets a number of these, at least of the moral sort since (naturally) as a churchman he doesn't get involved in any action scenes. Of particular note is during Frollo's siege of the cathedral:
Archdeacon: Frollo, have you gone mad?! I will not tolerate this assault on the house of God!
When Phoebus gets Esmeralda to claim sanctuary so she is safe from Frollo. Not only does he stalk forward to interrupt just as Frollo is demanding Phoebus drag Esmeralda outside so he can arrest her, but then he lays a hand on her shoulder reassuringly and delivers a deceptively mild but delicious rebuke, referencing his "very eyes of Notre Dame" moment above:
Archdeacon: Don't worry, child. Minister Frollo learned years ago to respect the sanctity of the Church.
The look of impotent, teeth-gnashing fury on Frollo's face is wonderful.
Also, the glare of the Archdeacon when he said that line. Frollo may have feared the Archdeacon.
All the Archdeacon moments take a even more impressive gloss when you learn that in the original book Frollo is the Archdeacon, meaning that the Disney film can be said to use two characters to illustrate the internal debates that Frollo has, and therefore Frollo casting the Archdeacon down is equivalent to him discarding pretense of morality and what good might still remain in his own soul in order to enact his desires.
Quasimodo's incredible escape, rescue of Esmeralda from the stake, cries of "SANCTUARY", and the image of waterfalls of molten lead pouring from Notre Dame.
Quasi slumps down in chains when Frollo is about to burn Esmeralda, then slowly looks up. As Frollo sets the fire, Quasi lets out a tremendous "NOOOOO!" proceeding to break the chains, save the girl, and kick some arse. He shakes the entire cathedral with his exertions!
The filmmakers considered the entire movie an elaborate prologue for that very moment.
There's no way this scene isn't epic. Just read it:
[Quasimodo is chained down, the gargoyles are trying to free him]
Hugo: Come on, Quasi, snap out of it!
Victor: Your friends are down there!
Quasimodo: [despondently] It's all my fault.
Laverne: [as she, Hugo, and Victor try tugging the chains] You gotta break these chains!
Quasimodo: [sulkingly] I can't. I tried. What difference would it make?
Victor: But you can't let Frollo *win*!
Quasimodo: [despondently again] He already has.
Hugo: [dropping the chains] Say, you're giving up? That's it?
Laverne: These chains aren't what's holding you back, Quasimodo.
Quasimodo: [snapping] Leave me alone.
Hugo: [meekly] Okay. Okay, Quasi. We'll leave you alone.
Victor: After all, we're only made out of stone.
[he and Hugo turn to stone]
Laverne: We just thought maybe you were made of somethin' stronger.
[turns to stone]
Laverne: [pause; Frollo's voice drifts up from below]
Frollo:For justice, for Paris, and for her own salvation, it is my sacred duty to send this unholy demon... back where she belongs!
[he fires the kindling while the crowd indistinctly shouts in protest]
Give Esmeralda some credit. When Frollo tells her how she can get out of being burned by having sex with him, her response was to spit in his face and give him a Death Glare.
Esmeralda stops the crowd from tormenting Quasimodo and tells Frollo where to shove it when he orders her to stop.
Esmerelda: You mistreat this poor boy the same way you mistreat my people. You speak of justice, yet you are cruel to those most in need of your help.
For added awesomeness, the scene where she escapes with gusto, doubling as a Funny Moment. Anybody who thinks all Disney women are weaklings shall henceforth be directed to that scene.
Esmeralda: Let's see... *counts the guards* onetwothreefourfivesixseveneightnine... so there's ten of you and one of me. *pulls a handkerchief out of her blouse* What's a poor girl to do? *affected sobbing*
Big Bad Judge Claude Frollo's smug (and awfully ironic) Last Words, "AND HE SHALL SMITE THE WICKED AND PLUNGE THEM INTO THE FIERY PIT!!!"
After Frollo's last words, the face the Gargoyle makes just before the plunge seems to say "Hey, there's an idea!"
By this point, Frollo had grown to be so evil, that some Youtube comments has interpreted that scene as God descending into Hell and granting Lucifer permission to enter his highest cathedralto personally collect Frollo's soul!!
The Youtube Comments are backed up by the fact that when Frollo loses his balance and is holding onto the gargoyle, as it springs to life, the choir sings "Kyrie Eleison" (Lord have Mercy). God probably would show Frollo as much mercy as Frollo has shown others.
When you consider the Archdeacon saying Frollo learned to respect the sanctity of the church, and he spent the entire scene attacking it and violating sanctuary... well, that ladies and gentleman is what happens to those who don't respect the sanctity of the church.
They remade this scene in Kingdom Hearts 3D, not once, but twice! The first time is once you beat the boss as Sora, which shows the movie version, the second time is before you fight the boss as Riku, where the force of the Nightmare flying just causes Frollo to fall, all while he happily claims "Judgment is mine!!"
Esmeralda deserves a mention for that scene as well. Despite being weakened from smoke inhalation (and probably rough handling too), she still does her best to hold Quasimodo up on the ledge. Even Frollo standing above her with his sword raised doesn't make her let go.
Phoebus refuses Frollo's order to burn down the miller's house, saves the miller's family after Frollo sets fire to the house anyway, and runs away by stealing Frollo's horse!
The method in which he saves the family is is worth mentioning. He rolls out of the way of a falling beam, dives headfirst through a glass window, then emerges from the burning house by Sparta-punting open the door, while holding the miller's two young children. Definitely elevated Phoebus from generic Disney male love interest to a much more developed and compelling (not to mention Badass) character.
This exchange, just before Esmerelda saves him from being executed, simply seals the moment:
Frollo: Such a pity. You threw away a promising career.
Quasi and Phoebus: [gagged and about to be hanged] Mmmmphhff!
Clopin: [rolling his eyes and giving an Aside Glance] That's what they all say.
Quasimodo's Kubrick Stare as he decides that he's had enough of Frollo's crap when he's chained up in the cathedral.
Quasimodo's Calling the Old Man Out speech; Frollo has treated him like garbage for 20 years, to the point where Quasimodo just weakly obeys his will. This is essentially when Quasimodo is saying "screw you, I'm not listening to you anymore."and finally stands up for himself (although breaking out of the cathedral and saving Esmeralda was definitely the first massive step in the right direction.)
Quasimodo: No! You listen! All my life you've told me that the world is a dark, cruel place. Now I see that the only thing dark and cruel about it is people like you!
The look on Frollo's face as he realizes that a) he no longer has any influence over Quasimodo, who is b) less than half his age, c) strong enough to break his spine like kindling and oh yeah, d) really pissed off right now makes it even more satisfying. All Frollo can do is feebly stammer "Now. . .now, listen to me, Quasimodo. . ." Frollo really was a coward and now all the abuse over Frollo will come back to bite him
On top of that is something most people are going to miss. Right as Quasimodo calls the old man out on being dark and cruel, Quasi throws down the knife that he just wrestled away from the psycho. One of the many signs of just how different the two of them are; Frollo would have not hesitated to shank his adopted son if their positions were reversed.
"Out There". The whole song just makes you so grateful to be alive. Not to mention Tom Hulce's singing voice is JUST AWESOME!
"God Help The Outcasts". To understand how Awesome this song is, first, understand that Sanctuary only applies for forty days, at which point, the offender must surrender peacefully, and may be sentenced after such period (at the best, she would have been deported, which we have to believe is a worse fate than staying in Paris under Frollo's rule, and at worst a death sentence). Further more, she is admittedly not Christian ("I don't know if you can hear me, or if you are even there.") so Sanctuary doesn't really apply to her. Compound to the fact that the Archdecon is not legally obligated to feed her, and armed guards are waiting at every point to catch her if she leaves the church, Esmerelda is in a desperate state and deserves her "I Want" Song to be answered. So, what does she want in her "I Want" Song? She asks God to not worry about her, cause she can take care of herself, and instead says she wants him to look out for people in much more desperate situations. Keep in mind, this Non-Christian is schooling devout Catholics who ask for money, love, glory, ect. in the art of prayer.
Despite everything Frollo put Quasi through, including just trying to kill him and revealing the truth about how Quasi's mother died, Quasimodo is trying desperately to hang on to Frollo, he doesn't want to kill him, even though if he did let Frollo fall to his death it would be justified.
It's beautiful how subtle it is represented. Most other films place emphasis on how the hero refuses to kill the villain, but here it's simply the refusal to let go, without any acknowledgement in dialogue.
"No soldiers! Sanctuary! Get OUT!" Do NOT make Quasimodo angry. Also, how he lifted Phoebus off the ground, his strength is a CMOA of itself. To elaborate: He lifts a relatively tall and muscular man. Wearing plate armor. With one hand. You do NOT fuck with Quasi.
Quasimodo's mother deserves a mention; she managed to stay ahead of a galloping horse in the middle of winter - with plenty of snow on the ground that she could have slipped on - leap a railing to try to escape Frollo, and have enough presence of mind to get to the cathedral and claim sanctuary. All while carrying baby Quasimodo!
