Accidental Innuendo: When the dwarfs meet Snow White for the first time, Grumpy tells Doc to "Ask her who she is and what she's a-doin' here!" Of course, given his tendency to get words mixed up, Doc comes out with "What are you andwho are you doin'?" Surprisingly enough, given the time period this film was made in, this is probably one of the earliest examples of this trope.
Snow White, depending on how you view her, is either way too polite and altruistic for her own good or just plain Too Dumb to Live.
Also, The Queen in The Book "Fairest of All"; an extremely dark Woobie, Destroyer of Worlds (to Kefka levels) who, after being reexposed to mental anguish caused by her father regarding not being beautiful at all and an extremely low self-esteem left her so broken and insane that she felt that killing her stepdaughter was the only thing left to match up to her abusive father's standards of beauty. Seems to nudge to the direction of the latter.
Dopey might be an Idiot Savant, having difficulty in doing simple things but being a vastly accomplished musician.
"The Silly Song" segment slightly justified in that they are celebrating Snow White and it leads to them wanting Snow White to tell them a story leading to one of the most memorable songs ever (Someday My Prince Will Come).
There was a segment planned where the Dwarfs have soup after washing their hands and sing a song about... soup. If it had been put in the final product, it would have qualified for this trope!
The Tree hallucination; it's quickly forgotten after Snow White finds her little forest friends.
The Dwarfs in general, being distinct in personality and very humorous as well.
Dopey, particularly around the time the film was originally released. Many predicted that he would become as big as Mickey Mouse and Donald Duck. It didn't quite turn out like that, but still, to think that it might have is impressive. Dopey was, in fact, the initial choice for the apprentice role in the Sorcerer's Apprentice sequence from Fantasia. He was replaced because Donald was the public's favorite Disney character at the time, and Walt Disney wanted Mickey back in that seat.
Grumpy seems to have amassed a big following in recent times, to the point where a reasonable amount of merchandise is dedicated to him and his sourpuss attitude.
Evil Is Sexy: The Queen, until she transforms herself into the hag.
Genius Bonus: When the Dwarfs forcibly wash Grumpy and put a ring of flowers on his head, Sneezy comments that he smells like a petunia. In botany, petunias symbolize anger and resentment, meaningful if your name happens to be Grumpy.
Growing the Beard: This marks Disney's change from whimsical cartoons and into the full length, animated film genre capable of telling a longer, more complex story, not to mention the animation quality is a drastic improvement of the previous shorts.
Harsher in Hindsight: Snow White wonders if the seven "children" don't know how to clean because they don't have a mother and are orphans. While saying how awful that would be, a fawn nuzzles its mother.
There are references to other Grimm fairy tales throughout the film. Initially, Snow White is forced to wear rags and work as a scullery maid, like Cinderella, and in case you overlooked the reference, she even has a flock of doves helping her like in the Grimm version. Later, the prince awakens Snow White with a kiss, which was borrowed from the Grimms' retelling of Sleeping Beauty, as in the original Snow White merely coughs up the apple. Cinderella and Sleeping Beauty were respectively the next fairy tales Disney would adapt in films (and all three were the only fairy tale films Walt himself was still alive to work on).
Moral Event Horizon: The Queen definitely crosses it: She wants to kill an innocent girl (who is probably 16 or lessnote The Disney Princess material states that she is the youngest Princess, at 14) and for what?!? Just because she's more beautiful than her. And if that's not enough she plans to poison her with the Poison Apple making her fall into the Sleeping Death hoping the dwarves will bury her alive.
And it was also originally planned that she tried to force the Prince - the guy who loved Snow and who Snow pined after - to marry her. And when he refused, she would try to drown him in the dungeon.
The Queen crossed it long ago when she hired a huntsman to try and kill Snow White. How? Because she tells the hunter that in order to make sure Snow White's dead, she asks him to cut her heart out and put it in a box to present her with! And remember - this is her stepdaughter we're talking about.
The fact that Snow White herself looks and sounds no older than 14, and the prince's voice places him as quite a bit older than that. Justified in that it was normal for people to get married at a young age in the time period the film takes place, but still, to a modern audience, it may come off as creepy.
Virtually any scene of significance in this movie has been copied, homaged, parodied and ripped off incessantly for over 70 years. Best advice to parents is to show it to the kids quickly.
Many see this as "just another sappyDisney Princess film", failing to realize how truly groundbreaking a project this was when released.
Fans of Disney Princess films often find this film boring and bland compared to future films. This film started and paved the way for much of the material in future Princess films.
Squick: Sneezy's deleted line in "The Silly Song" where he mentions that after he was born, he used his whiskers as a "didee"note (diaper). The effect is somewhat lessened by him sneezing while delivering the line but it's still unsanitary.
Tastes Like Diabetes: Snow White. Many people find her exaggerated Moe traits and sickeningly sweet attitude insufferable.
What an Idiot: As Cracked pointed out, the Queen could have just actually killed Snow White instead of betting on her sleeping forever. Especially since she would just retain her beauty that way.
Being buried alive would kill Snow White, according to the "Buried Alive" myth tested by the MythBusters.
What Do You Mean, It's Not for Kids?: Possibly the Ur-Example. In fact, Walt never intended "Disney" to become synonymous with being kid-friendly (family-friendly, yes, but not kid-friendly. "Family-friendly" implies that it's adult, but still respects its child audience by not going too far). Animation was just easier for all the detail he wanted to include in the story.
