Animal Motifs: The Queen's thematic ball, where her dress resembles a peacock, Snow White's resembles a swan, and Prince Alcott's hat has rabbit ears. The Alternate Character Interpretation inherent in the rabbit costume is discussed by the Queen and the Prince.
Animal Stereotypes: The vanity peacock, the purity swan, the nervous (but smarter and more dangerous than he appears) rabbit.
Arc Words: The Queen's "Snow White would have to do what snow does best. Snow... would have to fall."
Arranged Marriage: Aware that he comes from a wealthy kingdom, the Queen plots to marry Prince Alcott to solve her own financial problems.
Broke Episode: The Queen's greed and exaggerations pretty much bankrupted the kingdom — people are literally begging for food on the streets, because what litttle money they have is taken to pay the Queen's taxes.
Disproportionate Retribution: The Queen is very harsh on her punishments. "A Royal Decree, take it down. Any busybodies caught rumouring, gossiping, whispering, or even thinking... shall be put to death."
Dissonant Serenity: The mirror, who never appears to be more than faintly bemused no matter what happens.
Snow White spends a few seconds staring at him while his hands are tied before asking if he needs help
"Seeing you in this dress is causing me to lose my words"
Distressed Damsel: Averted. Snow White refuses to be one, evoking the trope by mentioning she has read many stories in which the damsel has to be saved by her prince, but she doesn't want that to happen.
Distressed Dude: Alcott, on the other hand, is frequently overwhelmed by danger — he's mugged and hanged upside down by the dwarfs (twice), hypnotized by the Queen into nearly marrying her, viciously attacked by the Beast and ultimately pinned down by it against a tree. Doubles with Badass in Distress, as he's also shown to be pretty capable and a very good fighter.
Don't Go in the Woods: It's not truly forbidden, but commonly known to be dangerous, as the vicious Beast lives there. According to the dwarfs, it doesn't usually leave a specific side of the forest, though.
The Dragon: It was obvious Brighton wasn't up to this, and the Queen eventually reveals the Beast is her true Dragon.
Driven to Suicide: The Queen eats the poisoned apple at the end when she realizes she's been beaten. This also destroys her mirror self.
Dual Wielding: Both Snow White and Prince Alcott wield two swords at some point.
Endless Winter: Winter falls over the land when the evil queen starts to rule. It ends when she is defeated.
Grimm, the ex-teacher, who is the logical leader of the group is Doc.
Butcher, the mean, emotional leader of the group, is Grumpy.
Chuckles, who is always laughing, is Happy.
Half Pint, like Dopey, is most in love with Snow White and is too stupid to get that she doesn't feel the same.
Napolean is a hopeless romantic, like Bashful, as can be seen in the kissing scene.
Grubb represents Gluttony in the same way that Sleepy represents Sloth.
Wolf is always Howling just like Sneezy is always Sneezing.
Faceless Goons: The Queen's soldiers use golden helmets concealing their faces.
Fairest of Them All: Evoked by the Queen, referred to by the mirror. Oddly enough, the Queen never directly asks the mirror on-screen — and thus it never tells her Snow White is fairer than she is, though it does warn the Queen.
Mirror: I suggest you marry someone rich, quickly. Because one day soon, you will ask me who the Fairest of Them All is... and you won't like the answer.
Female Gaze: "Oh my God, can someone please get this man a shirt so I can concentrate!"
Similarly, the guards, unsure of whether or not they are supposed to stop Snow White from leaving the Castle, agree to let her out, and not to tell anyone about it.
Lighter and Softer: A comedic take on the fairy tale compared to the other live-action one coming out the same year. Though not played entirely straight; at the end Snow White encourages the Queen to commit suicide and it is implied she does.
Love at First Sight: Snow White and Alcott have shades of this. They seem to really fall in love during the ball, though.
The fact that he was shirtless when they first met probably helped.
Love Potion: The Queen mentions having used it on the King, and does in again on Alcott — though she ends up making him drink "puppy love" potion, it nonetheless makes him fiercely in love with her.
Meaningful Echo: "And the Queen realized that if she wanted to remain the most beautiful woman in all the land, snow would have to do what snow does best. Snow... would have... to fall."
Mix-and-Match Critters: The Beast is similar in shape to a wyvern or an Eastern Dragon but has the antlers of a deer, a furry mammalian face, feathered wings, bird-like feet, and a lizard-like tail (with a strange claw on it).
Queen: Her hair isn't "black", it's "raven". And her skin has never seen the sun so of course it's good.
Refuge in Audacity: Even after being turned into an old hag by her extensive use of magic, the Queen doesn't give up on killing Snow White: she takes advantage of her completely different look to sneak into her wedding unobserved and try to make her eat the poisoned apple.
Servile Snarker: The Palace servants. Lampshaded by the Queen once or twice. Even Brighton gets a moment after his Cochroach episode. The Queen appears to let them get away with far more than the noblemen without comment.
Talking to Themself: It was clarified by Tarsem Singh that the world of the mirror is the Queen's "mindscape", and she's basically talking to herself every time she talks to the mirror. In the movie, the mirror claims to be just the Queen's "reflection".
Trailers Always Spoil: Snow White leading the dwarf bandits, Snow White and Alcott duelling, the Queen hypnotizing Alcott through a love potion, it being really a "puppy love" potion, Snow White mobilizing the dwarfs to crash the Queen's wedding with Alcott. Seriously, guys, for a movie in which one of the first lines is "loose lips sink ships"...
You Can't Thwart Stage One: The Queen's plot to marry Alcott goes reasonably well until dangerously close to the end — Snow White and the dwarfs manage to crash her wedding, kidnap the Prince and flee moments before the Queen arrives. And they still have to deal with the love spell after that.
