Mulan: A reprise of "Make A Man Out Of You" plays with unabashed glee while Mulan's friends are getting tarted up in full concubine drag to infiltrate the palace. Later, all four of them actually use the combat moves they were shown learning during that musical number against the Huns... still dressed as women.
"I work alone." In a visual echo, the first time we see the family using their powers together, they are fighting with each other until interrupted by Frozone. The next time, they are fighting with Syndrome's goons until interrupted by Syndrome.
It's claimed that Omnidroid v9 "got smart enough that it wondered why it had to take orders". This probably wasn't true for Omnidroid v9, but it was most certainly true for v10
Toy Story: "It's not flying, it's falling with style!"
After Buzz disbelieves "You. Are. A. TOY!" in the first movie proclaimed by Woody, he tries to persuade Woody to come with him by using the same line.
"You have saved our lives. We are eternally grateful."
The Simpsons Movie: Homer tells Marge that "in every marriage, you get one chance to say 'I need you to do this with me'" in order to convince her to join him in Alaska. Later, Marge says the same thing to Homer to get him to join her in saving Springfield. Homer's response: "That was the stupidest thing I've ever heard."
Aladdin: Genie says, "PHENOMENAL COSMIC POWER!...itty-bitty living space."
The Emperor's New Groove has a scene near the beginning where Kuzco fires Yzma for trying to run the country behind his back, and rattles off a Hurricane of Euphemisms for being fired ("'You're being let go.' 'Your department's being downsized.' 'You're part of an outplacement.' 'We're going in a different direction.' 'We're not picking up your option.' Take your pick. I got more.") Near the end of the film, Yzma has Kuzco cornered, and rattles off a similar Hurricane of Euphemisms for death, quoted at the top of the main Ironic Echo page.
As well as "nobody's that heartless."
Pacha: Deep down, I think you'll realize that you're forcing an entire village out of their homes just for you. Kuzco: And that's...bad? Pacha: Well, yeah. Nobody's that heartless. (Later...) Pacha:(after Kuzco saves him from a collapsing cliff) You coulda just let me fall. Kuzco: What's the big deal? Nobody's that heartless!
From Pocahontas: Upon seeing Wiggins, his manservant, not realizing what a "proper English greeting" was ("Ooh! gift baskets!"), Radcliffe sighs, "And he came so highly recommended." Cut to the end, where Radcliffe is arrested for attempted murder and being carted back to England in chains. Wiggins dabs at his eyes with a handkerchief and sighs, "And he came so highly recommended." Bonus points for Wiggins and Radcliffe having the same voice actor.
In The Iron Giant, Kent Mansley appends "and all that that implies" to several of his sentences for added emphasis. Towards the end of the film, when Hogarth thinks he's gotten rid of the nosy government agent for good, he smugly says to himself, "Bye, Kent, and all that that implies."
Something similar happened after Kent Mansley, in a panic, had the submarine launch a nuke at the Iron Giant while he was in the town, thus endangering the populace. The Iron Giant tells Hogarth "You stay... I go... No following." when he is going to go up through the atmosphere to intercept the missile, and probably sacrifice himself in the process. Hogarth said those exact words to the Iron Giant earlier in the film when he was going to call it a day (primarily because he didn't think his mom, never mind the rest of the populace in his town, would handle it well.)
The Lion King has young Simba going into an elephant graveyard, proclaiming, "Danger? Hah! I walk on the wild side. I laugh in the face of danger. Ha ha ha ha!" After the Time Skip and adult Simba's return to his kingdom, Nala taunts him by repeating "I laugh in the face of danger", complete with laugh.
Scar tells young Simba at his father's death to "Run away, and never return." Later, when adult Simba gets the upper paw over Scar, he repeats those words back to him.
Given that Scar's earlier use of those words also had him dispatching the Hyenas to kill Simba shortly thereafter, and Scar probably concluding that Simba would probably do something similar to Scar if he left, that might explain why Scar chose to attack Simba instead of heeding his advice to flee.
"Slimy, yet satisfying". Pumbaa's incentive to eating insects, and Simba's same response a few moments later after reluctantly trying one himself.
When young Simba says "When I'm King, I can do whatever I want," it's clearly a sign of his immaturity. When Scar says a variation much later, we know exactly why the Pride Lands went to hell under his rule.
When Timon and Pumbaa are first trying to persuade Simba that eating bugs is a good thing, Pumbaa declares, "You'll learn to love 'em!" Later, after adult Simba meets adult Nala and has to chase Timon and Pumbaa off so as to have alone time with her, he says, "Timon and Pumbaa—you learn to love 'em!"
In The Princess and the Frog, the key change of Dr. Facilier's epic Villain Song, Friends on the Other Side, contains a very powerful rhythm accompanying the phrase "Are you ready? Are you ready?" right before Prince Naveen becomes a frog. Later in the film, during Dr. Facilier's absolutely terrifying death, the shadows again start up the rhythm and sing "Are you ready?", to which he cries no, he's not, he needs more time... and keeps screaming this as he's dragged to his death.
Also, toward the end of the film, Dr. Facilier attempts to tempt Tiana with the restaurant of her dreams, repeating a line from Tiana's "I Want" Song.
In Bolt, we're introduced to Mittens the cat when we see her extorting food from some pigeons in exchange for not eating them. When one of the pigeons, Louie, is unable to bring anything but an orange seed, Mittens demands that Louie bring her all his food next time, or else. Louie protests "We had a deal!", to which Mittens replies "The deal's just expired." A few scenes later Bolt, believing Mittens to be an agent of "the man with the green eye" (the villain of the Show Within a Show on which he works), threatens her into telling him where Penny is. She convinces Bolt to head to Hollywood, California, but ends up getting dragged along by Bolt. When she protests "We had a deal!", Bolt replies "The deal's just expired." This is lampshaded when Louie, watching in amusement with his fellow pigeons, remarks "That's what she said to me earlier."
Lilo: "Ohana means family. Family means no one gets left behind. Or forgotten.
In Robin Hood, a character had once joked that if Robin marries Lady Marian, King Richard would have an outlaw as an inlaw. At the end of the movie, King Richard says the exact phrase during Robin and Marian's wedding.
Antz has the unprecedented use of Ironic Echo between a few seconds in regards to Z and General Mandible. As such, both are to be posted:
General Mandible: [Z has broken through to the surface where Mandible and his soldiers wait for them to be drowned] Let go! Don't you understand? It's for the good of the colony!
Z: What are you saying? We are the colony!
[Mandible is about to strike Z when Cutter knocks him aside]
General Mandible: Cutter, what are you doing?
Colonel Cutter: Something I should have done a long time ago.
[extends his hand to the worker ants]
Colonel Cutter: *This* is for the good of the colony, General.'''
The line "I did this" was said first by Hiccup upon realizing he couldn't bring himself to kill Toothless and again by Stoick when he thinks Hiccup is dead. Bonus points for having Toothless in both scenes and in the same position.
"You just gestured to all of me..."
"Thank you, for summing that up."
"That's for ______. And that's for everything else" Spoken by Astrid, when she hit Hiccup twice for keeping secrets, again when Hiccup drops her off after taking her to fly, only this time she kisses him the second time, instead of hitting him, and one last time at the end when she kisses him again.
"We're Vikings. It's an occupational hazard."
"Night Fury! Get down!" Spoken first when the Night Fury is attacking, and later when Toothless jumps on the villagers, playfully.
The phrase "New arrival", first used when Mayhew arrives in the Land of the Dead, is given a sinister tone after Lord Barkis accidentally kills himself by drinking the poison meant for Victor in an ironic toast to Emily. This makes him fair game to the dead, who descend in an angry mob to carry out a Fate Worse than Death.
In The Curse of the Were-Rabbit, there is an actual mute Ironic Echo. Gromit wants to leave his truck to help Wallace, but Phillip shakes his head "no", keeping him in. A minute after, when Wallace transforms, Phillip wants to shelter in the truck, but Gromit shakes his head in the same fashion and keeps the doors closed.
Hoodwinked: During Red's story, she calls Granny at a roadside payphone, and this exchange:
Granny Puckett: A trip up the mountain is too dangerous for a little girl.
Red Puckett: I'm not so little anymore!
In the next scene, when Red is in the treehouse:
Woodpecker: Are you going somewhere far away?
Red Puckett: No, the world is too dangerous for me! (throws her magazine over the side, which lands on a car and causes the driver to run into a tree)
Also, there's the Wolf's "Never trust a bunny" line. The first time, during his story, he's saying this to Twitchy after they make the mistake of trusting Boingo for directions to Granny's house, causing them to end up in a cave inhabited with bats. Here, the line is used in the context of navigation (well, he DOES tell them the route involves going over the woods and through the river). When Flippers makes The Reveal that Boingo was the Big Bad, the Wolf repeats this line, but this time referring to Boingo's deceptive appearance.
Monsters University: "There're always hiring in the mail room." First time is a mocking insult. Second time, it's brought in a hopeful, optimistic light.
In Swan Princess, when they first meet as children, Odette says in a resigned voice, "So happy to be here", to Derek, clearly not meaning it. When they became adults and are reunited, she says it again with sincerity during her Love Epiphany.
