The whole movie qualifies. At the time it was made a feature-length animated film was nothing short of miraculous. The fact that Walt and Co. made such a stunning and enjoyable one was an outcome no one planned on. "Disney's Folly" indeed!
Expanding upon this; yes, Disney had Mickey and various other successes prior of course but this was the film that paved the foundations for what we know now as Disney the film studio. Heck, it borders on being that literally as the profits from this film are what built the very studio in Burbank that's still its headquarters today. There was no feature-length film at the time apart from satire shows, mostly deleted, let alone in colors! This movie marked a new era, resulting the starting point in the animation we've come to know over the course of 85 years since its release.
Also attending the premiere was Clark Gable of Gone With The Wind fame, who was said to have been moved to Tears of Joy upon the film's conclusion.
The huntsman sparing Snow White's life. He knows he will face the consequences if he doesn't go through with it but when he sees her scared face, he drops the knife and warns her about the Queen. That took guts.
A 14-year-old girl who was chased out of her home by her only family, who had just tried having her murdered, into a forest of pure Nightmare Fuel with no food or friends and nowhere to go. She was ashamed of the fact that she was noticeably upset instead of keeping up her normally cheerful demeanor. She apologizes to the animals and it's only after she's comforted them with a song that she worries about herself. Snow White acts incredibly badass about the whole horrible situation.
Snow White and the animals cleaning the Dwarfs' filthy house. She doesn't know who owns the house but she takes it upon herself to do something good for them. Even more awesome given that Snow White has to correct the animals' attempts at chores (teaching the squirrel to shake the dust from its tail out of the window, etc.), she's able to coordinate a whole battalion of animals/people to teamwork flawlessly, doing something none of them had done before. Every animal was assigned tasks that they could do according to their abilities. That showcases Snow's skill as an organizer and leader - being able to talk to animals is one thing, creating an effective team out of them is quite another, as any leader of human teams can attest.
Snow White meeting Grumpy. Here's this crotchety little man giving her the stink eye and what does she do? She playfully sasses him.
Doc argues with Grumpy when he says that letting Snow White stay would be bad luck because "she's a female". In response, Doc says that's superstition, and Snow White is their guest! Turning her out in the cold would be violating Sacred Hospitality.
Snow White promises the dwarves that if they let her stay, she'll be no trouble. She can sew, clean, and cook; the dwarves then ask, Grumpy included if she can make apple dumplings. She says yes, and gooseberry pies as well! Unanimously, they say, "SHE STAYS!"
In a deleted scene, Snow White, seeing Grumpy and Doc getting into a fight over whether or not she stays, decides to leave, declaring that she'll find shelter elsewhere and that she's not afraid of the dark woods at night, not even "the goblins". In that one scene, she displays courage, sass, autonomy and shrewdness. An unexpected example of Silk Hiding Steel.
It's more like Nightmare Fuel, but the Queen's transformation is, for some fans, considered to be a fine piece of work, probably because of the effects that the animation creates. Effects which, at the time, were nothing short of miraculous.
When the Queen transforms herself into the hideous peddler. It was a huge challenge for the animators to not only depict her changing, but to show how she felt as she did. The result has served as pure terror for generations of kids, but it's also a truly awesome One-Winged Angel moment, and it shows just how evil she is - as suggested by Hans Conreid's Magic Mirror in the Disneyland TV show's "Our Unsung Villains" episode, she may be a Vain Sorceress, but her hatred for Snow is enough to trump even her vanity for a time ("just so you wouldn't get bored with this story"; the theme of the special was how villains are underappreciated for the conflict they provide that makes good drama). (Runner-up: her gleefully watching Snow succumb to the poisoned apple.)
Preceded by probably the most awesome and dramatic reading of a potion recipe since Macbeth:
Queen: "Mummy dust, to make me old. To shroud my clothes, the black of night. To age my voice, an old hag's cackle. To whiten my hair, a scream of fright. A blast of wind to fan my hate! A thunderbolt to mix it well! Now begin thy magic spell."
The sheer fact that The Queen breaks from her Evil Gloating to have a moment of lament, ensuring her spell has no overlooked detail. Sure she hand waves it when she discovers it, but still a chilling calculating side for one of Disney's first villains.
Queen: Then I'll be fairest in the land! (cackles but thenstops) But wait..! ...There may be an antidote. Nothing must be overlooked!
Another thing is that the Queen manages to row herself to the dwarves' cottage after the Mirror gives her a location. She arrives by her sheer stubbornness and determination. Remember that the birds had to guide Snow White to the same place.
During the Silly Song scene, the dwarfs are seen partying, singing and playing instruments, and Happy and Sneezy even make some yodeling. Who would have thought that the dwarfs were good musicians?
Since Dopey wants to dance with Snow White, he climbs up on Sneezy's head to be at the same height as her while wearing a human-sized overcoat, leading him to dance for three: he has to both keep up with Snow White's movements and keep Dopey balanced on his shoulders, but in the process, Sneezy and Dopey steal the show. In real life, this would be very uncomfortable and tiring, not to mention that it would probably be impossible, but despite the fact that he's supporting Dopey's whole body weight, carrying him and balancing him on his shoulders, Sneezy somehow still manages to dance, keep up the pace with Snow White during their dancing routine, run around and jump and make some impressive dance moves worthy of a professional dancer in perfect sync with Dopey. Bravo, Sneezy, terrific indeed! Too bad his sneeze puts the party to a halt, but when it blows Dopey away up to a column, it leads to a hilarious and memorable finale.
The confrontation between the dwarfs and the witch, for several reasons:
The dwarfs chasing the witch through the forest and up the mountain. And Grumpy's the one leading the charge!
Grumpy: "C'mon! GIDDYAP!!"
The witch's response? Push a giant boulder down onto them. She would have succeeded in killing Snow White and the dwarfs if not for a random bolt of lightning.
The execution is equally epic. The dwarfs frantically arrive just in time to see her sneaking out of the house and chase after her enraged. She eventually makes her way up to the cliff, her terror towards her doomed position slowly turning into venomous fury ("Trapped! What will I do...the meddling fools!...I'll FIX YOU! I'LL CRUSH YOUR BONES!!!"). Refusing to be taken out by a bunch of Not So Weak dwarfs, she begins to dislodge a nearby boulder, turning the tableson them, laughing manically in triumph until she is struck down by fate itself with an ear piercing scream and seemingly crushed by her own devices. Extra points for the shots of the vultures, gleefully awaiting to make a meal out of the fallen side throughout. The Disney Villain Death would be used often throughout the years, and this was the first and perhaps most climatic exit of them all.
, which opens with an epic montage of the Disney Animated Canon up to 1992's Aladdin, which would not have been possible without the one that started it all.
