Jafar's reprise of "Prince Ali". "Prince Ali, Yes, it is he, But not as you know him."
"One Jump Ahead" and its reprise also qualify: in the first Aladdin sings about what a great thief he is, in the second he wishes people saw that there was more to him than that.
When Genie puts the palace on the mountain, a sinister slowed down version of "Friend Like Me" plays.
"Why Me" was a rejected alternate reprise of "Prince Ali". In the stage adaptation, it was used as Jafar's introductory song.
In the third movie Aladdin and the King of Thieves, everyone is singing about Aladdin and Jasmine's upcoming wedding, but in the middle, it's a slow Distant Duet between Aladdin and Jasmine nervous about the changes going on in their lives.
"Who's Been Painting My Roses Red?" from Alice in Wonderland, an accusatory reprise of the cheerful "Painting the Roses Red".
"Gaston" starts out as an amusing but mostly harmless comedy piece, touting Gaston's "virtues" from the inane ("no-one's got a swell cleft in his chin like Gaston") to the unpleasant yet still funny ("in a wrestling match, nobody bites like Gaston!"). In the reprise, although the tune remains the same, all pretense is stripped away to openly trumpet Gaston's villainy. ("No-one persecutes harmless crackpots like Gaston!") There's a few Dark Instrumental Reprises in later scenes, such as when Gaston and LeFou visit Monsieur D'Arque and when he first encounters the Beast in the tower.
"Death of the Beast" is a sad instrumental reprise of "Beauty and the Beast" and the Beast's leitmotif, and had a rejected alternate version that was considered too light.
"The Mob Song" seems to follow the same melody as "Be Our Guest," with both the melody and material significantly darker.
In Cinderella, after the stepsisters rip up Cinderella's dress, dashing any of her chances to go to the ball, and Cinderella goes into the garden to cry, a somber offscreen chorus sings "A Dream is a Wish Your Heart Makes" while Cinderella has a Heroic BSoD lamenting that she's lost all hope (or so she thinks).
"Breakout/It Comes With a Pool" from Dinosaur, which is a dark reprise of "Courtship." It's played during the scene where Aladar, the Lemurs, Eema, Baylene, and Url accidentally discover an alternate route to the Nesting Grounds while attempting to find their way out of a large cave. The reprise comes in when Zini the lemur starts to surf in the lake, and the dark part comes in when Eema actually tells Aladar that the old entrance to the Nesting Grounds has been blocked by a huge landslide, and that Kron is threatening all the other dinosaurs into taking that route.
Also "Across the Desert", which is a slow and somber version of "Raptors/Aladar Meets the Herd". It's played during the scene where Kron forces the Herd (as well as Aladar, the Lemurs, Eema, Baylene, and Url) to march across an endless desert reminiscent of the final act of ''The Rite of Spring''. Fortunately, there's a lake ahead...
In Dumbo, following the Pyramid of Pachyderms disaster, Casey Jr. mournfully hums some bars from his otherwise cheerful theme song.
"For The First Time in Forever" has a reprise where Anna confronts her sister and tries to convince her to come home and end the winter she made. After Elsa learns she created an endless winter, she starts to panic, her singing quickly drowning out Anna's and ending with her accidentally striking Anna in the heart with her powers.
There's a melodic reprise of "Frozen Heart" as well at the end of that song which is appropriate because Anna now literally has a frozen heart.
"Do You Want To Build A Snowman?" morphs into a Dark Reprise of itself in the final verse. It begins as an upbeat song where the young Anna tries to get her sister to come out and play. The singing stops in the middle to depict their parents dying in a shipwreck. A final verse is then sung by Anna, pleading Elsa to let her in - sorrowfully ending on a tearful delivery of the line "do you want to build a snowman?"
The cut duet between Elsa and Anna, "Life's Too Short", had its own Dark Reprise. In a way it's also a dark reprise to "Do You Wanna Build A Snowman?" as it uses its melody. While Anna is slowly dying and Elsa is imprisoned in the castle's dungeon, they sing about their regrets. While the original is them arguing about how life's too short to put up with one another, the reprise is them realizing that life's too short to fight each other. Anna sounds painfully like she can barely breathe at the end of the song, implying it ended right before Olaf's scene.
An even earlier Cut Song "We Know Better" had a dark reprise. The first portion is about Anna and Elsa growing up together as little kids, having fun and making mischief. The dark reprise begins with civilians doubting Elsa due to her bold personality and frightening powers. Anna and Elsa begin to drift apart as the song goes on while people detest Elsa more and more. It ends with Elsa and Anna discussing princes - with Elsa being distasteful towards them while Anna adores the idea of falling in love - and Elsa repeats the chorus by herself.
On a score-related note, Hans has a leitmotif during the scene where he first meets Anna. After it's revealed that he's the Big Bad, the theme plays again with a more sinister tone.
Frozen II: The score "Ghosts of Arendelle Past" contains a dramatic instrumental reprise of "Dive down deep into her sound. But not too far, or you'll be drowned" from "All Is Found" near the end when Elsa freezes in Ahtohallan.
The film features a lovesick Quasimodo singing about how he has finally found love after years of assuming he was unlovable (Heaven's Light). Not much later, these same lyrics are echoed with a new, bitter twist as he discovers this his newfound 'love' is more interested in her Knight in Shining Armor.
Quasimodo: I knew I'd never know That warm and loving glow Though I might wish with all my might No face as hideous as my face Was ever meant for Heaven's Light...
And seconds after the first instance, Frollo sings his own version, "Hellfire'', about his fury at and lust for Esmeralda.
In addition to the instant dark reprise, "Hellfire" doubles as Lyrical Dissonance. The Ominous Latin Chanting aka "Confiteor" is a general confession of sin recited at the beginning of Mass of the Roman Rite in the Roman Catholic Church. It is a strong contrast to Frollo's actual song.
Frollo: It's not my fault! (Choir: Mea culpa through my fault) Frollo: I'm not to blame! (Choir: Mea culpa through my fault) Frollo: It is the gypsy girl, the witch who sent this flame! (Choir: Mea maxima culpa through my most grievous fault)
"The Bare Necessities (Reprise)" from The Jungle Book. It's sung by Baloo and Bagheera as the two both walk off into the sunset after Mowgli bids them both farewell and heads back to the Man-village. Earlier in the film, there is another dark reprise of "The Bare Necessities". Mowgli sings it before Baloo reluctantly attempts to take him to the Man-village.
Scar was originally going to have a reprise of "Be Prepared". It started with the deleted scene of him trying to court Nala as his mate, then when she refuses and the pride refuses to banish her on Scar's behalf, he introduces them to the hyenas, who in this version had been denied the run of the Pride Lands for some time. They then sing a more traditional reprise of "Be Prepared", warning the lionesses that they now run the Pride Lands as they chase Nala away from home.
When Scar discloses his intent to kill Mufasa and Simba in "Be Prepared", the hyenas misread it to mean there would be no king at all, leading them to chant "No king! No king!" before Scar angrily corrects them. A choir can be heard singing an ominous reprise of this chant later as Mufasa struggles to save Simba during the wildebeest stampede, moments before being murdered by Scar.
In Mulan, the usually grand imperial theme plays in a somber tone after the army led by Shang's father is found annihilated by the Huns.
Near the end of Pinocchio, a much more somber and slower variation of "When You Wish Upon A Star" performed on a violin is briefly heard as Geppetto and the others are mourning Pinocchio after Pinocchio died saving Geppetto's life. This is but moments before the Blue Fairy appears and announces Pinocchio's sacrifice is what proves himself brave, truthful and unselfish, and she restores his life and turns him into a real boy.
"Colors of the Wind (Reprise)" from Pocahontas. It's a somber, instrumental version of the song "Colors of the Wind" that plays at the end of the film where John Smith is actually sent back to England as a result of him being shot by accident by the villain while attempting to protect the Indian chief.
First, Tiana sings her "I Want" Song "Almost There" a second time after she's outbid on the restaurant she wanted (or so the realtors claim). Plus a related Ironic Echo, when Facilier whispers this as he offers to help her in exchange for his talisman.
The reprise of "Mother Knows Best". That was already a dark Villain Song to begin with, showing Gothel emotionally abusing Rapunzel under a "good mother" facade. At the reprise Gothel has dropped the facade and is now outright hostile to Rapunzel. The fact that both are literally in the dark but the first time it's because Mother Gothel closes the curtains, and at the reprise it's because they're outside at night, can be symbolism for Mother Gothel dropping her facade: the darkness as well as Mother Gothel's attitude is artificial vs. natural.
The second reprise of "The Healing Incantation" as Rapunzel desperately tries to revive the mortally wounded Flynn after her hair has been robbed of its healing magic.
Turning Red: A more sombre version of Mei's theme plays when Mei is taken home after she attacks Tyler at his birthday party.
A darker version of the panda theme is also used when Ming, in her red panda form, attacks the 4*Town concert.
Wreck-It Ralph: The music that plays when the Sugar Rush characters bully Vanellope and destroy her kart is a darker version of the upbeat theme that plays during the roll-call for the race.
All Dogs Go to Heaven: A Christmas Carol, it manages to have a normal song paired with a Dark Reprise at the same time with I Always Get Emotional At Christmas Time. On one hand, Killer is singing about how he loves Christmas and it makes him feel repentant for his evil deeds while Belladonna's version has her singing about how much she loves doing evil things to people on Christmas.
The second film has the reprise of "It Feels So Good to be Bad", brief as it is. While the first song was simply Red singing about how Evil Feels Good and how doing evil things can give one pleasure, the reprise is about how the coming success of his plan to steal Gabriel's horn and send all dogs to hell makes him feel good about what he's doing at the expense of others. The kicker that truly makes this a dark reprise? Carface, the previous song's Chew Toy is singing along with Red, saying how "it's deeply pleasing to be the reason so many will be so sad".
The aptly titled "College of Broken Dreams", which segues into the BSoD Song, is an unhappy mashup of the songs "Better Life", "Beyond These Walls", "More More More" and "Follow Me Home", with more cynical lyrics.
And just in-between said moments when Arlo falls into the lake at Central Park before plunging into the sewer, the background score is playing a slow, more lustful instrumental reprise of the movie's prologue song, "New York, My Home".
Cats Don't Dance uses this trope with "Big and Loud". The first time, Darla is giving advice to Danny about how to impress an audience. Once Danny is hustled out the door, the lyrics change as she declares her true intent — to destroy Danny's career and that of anyone else who gets in her way. The first time she tells Danny, "[Your act]'s gotta be big and loud!" but it shifts to, "They're gonna fall big and loud!" The song is used a third time as she puts her plan into action, with the same lyrics as the second time, as she revels in her victory.
When Coraline visits the Other Mother's parallel world, she meets the other world's version of Mister Bobinsky (her strange yet friendly house neighbor), who performs his the "Mice Circus" song. Later, when Coraline heads back to retrieve the souls of the Other Mother's victims, she finds the circus in disrepair and the Other Mr. Bobinsky reduced to a pile of talking rats. The song accompanying this scene presents the feeling of a circus falling apart.
Likewise, when she revisits Spink and Forcible's burlesque theater, the bawdily silly song they'd earlier performed plays in the background, making for an unnerving contrast to the gloomy setting. Eventually, it becomes a twisted sort of ballet music.
During the song "Let There Be Snow" in Frosty Returns, Mr. Twitchell sings one with his own lyrics ("There's no more snow!") to an industrial metal version of the tune.
Inverted and played straight in How to Train Your Dragon. The music playing when Hiccup first encounters Toothless is a sinister version of the "Friendship Theme" played later in the movie. This does however get a true dark reprise during the scene where Hiccup accidentally betrays Toothless by telling Stoick that only a dragon can find the hidden island.
Also played straight with "Test Drive", originally heard when Hiccup is learning to ride Toothless. A sadder version comes later after Hiccup lost a leg during his fight with Red Death, and must learn to walk with a crude prosthetic limb.
The Dark Reprise is used to great effect in the second movie as well. The lovers' song that Stoick and Valka sing together with such enthusiasm and joy when they are reunited is later brought back during Stoick's Viking Funeral as a slower, sadder version with mournful background vocals singing during Gobber's farewell speech to his friend.
The LEGO Movie 2: The Second Part: "Everything's Not Awesome" starts as a dark reprise of "Everything Is Awesome" after everyone is trapped in the storage bin after Ourmamageddon and they start to lose hope, but turns into a Triumphant Reprise after Lucy inspires everyone not to give up.
Other:
Coco: While the first performance of "Remember Me" is a bombastic grandiose ballad, it reappears on a more melancholy note later in the film. In an inversion, the former is actually Ernesto's bastardized version stolen from Héctor, while the latter is how the song was meant to be played, as a farewell lullaby from Héctor to Coco.
"How Bad Can I Be?" from The Lorax (2012) was supposed to have one in the cut song "Biggering" where the Once-ler takes a flying leap off the slippery slope, becoming a villain who is totally aware of the carnage he's causing and choosing to ignore it, rather than the Obliviously EvilAnti-Villain he stays in the real movie. The piece was removed for being too dark.
Once-ler: Who cares if some things are dying? I don't wanna hear your crying!
In Mickey's Christmas Carol, the background music starting at Scrooge's arrival at the graveyard through Bob Cratchit's exit is mostly an instrumental sad reprise of the opening credits song, "Oh What a Merry Christmas Day".
The B-section of the Villain Song "Battle" is an evil counterpart to the chorus of the "Cafeteria Song" from the first EQUESTRIA GIRLS. This part gets an even darker arrangement in the Dazzlings' part of "Welcome to the Show", as mentioned in the Sarcastic Echo section.
When the Dazzlings have been defeated, they sing the "We will be adored..." part of "Welcome to the Show" horribly, as a result of all their powers gone when their ruby pendants have been destroyed.
In the My Friends Tigger & Pooh film Pooh's Super Sleuth Christmas Movie, there's "Christmas Isn't Coming," a sad reprise of the special's opening number "Christmas Comes Tomorrow," performed after the Sleuths and the rest of the cast, sans Darby, have given up the quest to reach the North Pole as hopeless.
In The Prince of Egypt, the song "The Plagues" is partially a dark reprise of Moses' earlier "I Want" Song inversion, "All I Ever Wanted", turning from a celebration of his life as an Egyptian to a lament over having to destroy it to win freedom for the Hebrew. It also doubles as a Villain Song for the Pharaoh, showing his anger at his foster brother's betrayal. Makes it even more dark and sadder if you remember that in-between "All I Ever Wanted" and "The Plagues", Moses' adoptive mother, the wife of the pharaoh, sings a reprise of this song, in a tender, motherly and comforting way, while trying to convince him to forget his true origin and embrace his Egyptian life and his adoptive family.
"My Kingdom of The Heart" from The Princess and the Pea. It was sung by Daria earlier as she and Rollo shared a Dance of Romance, and the reprise is sung when Rollo settles to marry Hildegard and Daria wanders around the forest after being exiled.
In Puss in Boots: The Last Wish, while burying his clothes for his 10-Minute Retirement, Puss tries to cheer himself up by singing his usual upbeat song "Fearless Hero"...only to break down sobbing over how badly his encounter with The Wolf traumatized him.
"I Stand Alone" in Quest for Camelot is Garrett's "I Am" Song in which he embraces his solitude and declares that he works alone. He gives it a brief but passionate Dark Reprise towards the end of the film, bitterly repeating the chorus as he unhappily resigns himself to remaining alone.
In the Chuck Jones adaptation of Rudyard Kipling's Rikki-Tikki-Tavi, Darzee's Chant gets a Dark Reprise when it is thought that Rikki has been killed offscreen by Nagaina. It then switches almost seamlessly into the triumphant original lyrics.
The song "First Toymaker to the King" from the Christmas SpecialSanta Claus Is Comin' to Town is reprised as "No More Toymakers to the King" by Burgermeister Meisterburger.
In The Spongebob Squarepants Movie, there's the Goofy Goober song. Sung at the beginning in a childish, sugary haze, it receives two dark reprises:
At the Thug Tug, the head thug realizes there are "babies" in their midst (i.e. SpongeBob and Patrick), and his method of weeding them out is to line everyone up and play the song at full volume, knowing that "no baby can resist singing along" to it. It becomes a full-on Dark Reprise when the thug, noticing the duo struggling to remain silent, leans right into their faces and starts singing the song in a taunting, sinister voice. They're a second away from breaking when another pair break first and are promptly set upon by everyone else in the bar, allowing them to escape unnoticed.
The song is reprised in a slower, lower key as the two main characters are literally being killed; by being dried up by the heat of a lamp's lightbulb shining over them.
"La Resistance" also provides a very short version of this for Satan's oddly poignantVillain Song, "Up There." The original has him sing "Up There there is so much room/Where babies burp and flowers bloom," while he adds in the reprise, "Tomorrow night Up There is doomed..."
Also in the song, the brief reprise of 'Uncle Fucker'—as Terrance and Phillip await their pending execution, they sing "Looks like we may be out of luck/Tomorrow night, we're pretty fucked!!"
The song "Let Me be Your Wings" has a dark reprise halfway through the movie, called "Once There was the Sun". She sings this in lamenting Cornelius' apparent death.
When Thumbelina goes missing, her mother sings a sad reprise of Thumbelina's "I Want" Song "Soon".
"Friends to the End (reprise)" from Tom and Jerry: The Movie, which plays when Tom and Jerry start to chase each other again, all without any dialogue.
Toy Story 3 begins with a montage of clips of Andy playing with his toys while 'You've Got a Friend in Me' plays, until suddenly the music stops and the line 'our friendship will never die' is the last line you hear.
Up: The first song heard in the film is Charles Muntz's theme, a jaunty and optimistic tune that represents the inspiration he brings to Carl and Ellie. When Carl meets Muntz at Paradise Falls and his theme returns, it gradually takes on a far more sinister tone as his true intentions are revealed.
WALL•E has an interestingly reversed version of this, with the "dark" version coming before the 'light' one. In the first act, the titular robot watches a video of "It Only Takes a Moment" from Hello, Dolly!, with the sappy romantic lyrics serving only to accentuate the hopeless loneliness of his existence. The song is used throughout the film as a Leitmotif, until at the very end of the film it gets a full reprise, only this time played straight.
" is a general confession of sin recited at the beginning of Mass of the Roman Rite in the Roman Catholic Church. It is a strong contrast to Frollo's actual song.Frollo: It's not my fault! (Choir: Mea culpa through my fault)
