The Pixar film contains examples of:

  • Award Snub: Up became the first animated film since Beauty and the Beast to be nominated for Best Picture at the Oscars. And it won...Best Animated Feature.
  • Ear Worm: They get a lot of mileage out of the main theme, constantly remixing to fit the film's current mood. And it's a great tune. Two reasons why it'll be stuck in your head for days.
  • "Funny Aneurysm" Moment: In less than three minutes. When they went to their picnic, it was so funny seeing Carl out of breath and unable to climb the hill. When the same happens to Ellie, it becomes bad news.
    • In the Norwegian dub, Carl's line early in the movie of only giving away his house "when [he's] dead!" becomes this when his Norwegian actor, Helge Reiss (who'd voiced in many Disney films), passed away of old age just a few months after the film's release.
    • The scene where Carl hits the construction worker on the head with his cane might be funny for some...until it's given very real consequences and ends up ruining Carl's life.
  • Genius Bonus: When Carl goes down in the stair lift, the music is la "Habanera" from Carmen, which is about how love is unpredictable. Some of the lyrics are "if you don't love me, I love you, but if I love you, beware". Carl doesn't like Russell or Doug but ends up loving them both; and he loves Muntz, who will try to kill him.
  • Harsher in Hindsight: After seeing Pete Docter's later film Inside Out, it very much comes off like Carl has the opposite problem of that film's Riley: his Sadness is firmly in control and refusing to let Joy have any input.
  • Hilarious in Hindsight: In the credits Carl and Co go to see a new Star Wars movie. Disney now owns Star Wars movie and they have ordered a new set of films to be made.
  • Hype Backlash: Critics and other moviegoers enjoyed the film so much that some other people's expectations were raised to the point where they didn't enjoy the film. Then again, the film's initial premise was what originally caused people's first expectations to be low.
    • Another very small contingent thought that the film's celebrated early montage was a piece of genius and thought that the rest couldn't quite compare.
  • Jerkass Woobie: Muntz—rejected by the scientific community, eluded by a stupid bird for sixty years, all by himself, going completely insane and paranoid... it's so tragic... Of course, murdering or even attempting to murder innocent people (his biggest fan and a child, no less) because he thought they would take his bird away makes him a bit of a monster.
  • Memetic Mutation:
    • The "Married Life" theme has become infamous for its tear-jerking capabilities.
    • SQUIRREL!!! So much so that "squirreling" has since become shorthand for "getting easily distracted."
    • Dug's "I have just met you, and I love you."
    • The "Still a better love story than Twilight." meme. The first ten minutes of the film showing Carl & Ellie's love story from their Meet Cute to Ellie's death are often regarded as a far more compelling love story than the entire Twilight series.
  • Moral Event Horizon: If Muntz not crossed this before when he started murdering tourists who came to visit Paradise Falls, he definitely crossed it when tries to kill Russell in cold blood.
  • Signature Scene: The first ten minutes chronicling Carl and Ellie's life together.
  • Spiritual Licensee: The "Married Life" montage is sometimes referred to as Pixar's best short film, as it could have the same exactly impact if it were one.
  • Sweet Dreams Fuel: The ending credits, with little tokens of Russell and Carl's friendship and lots of puppies.
  • Unintentionally Sympathetic: When Muntz sets fire to Carl's house and makes off with Kevin, Carl ignores the bird and tries fruitlessly to extinguish the blaze. Russell is outraged and yells at Carl for not caring about Kevin before running off on his own. Supposedly, Kevin is right to castigate Carl because the ultimate message is that Carl should let the past be the past and focus on continuing his life. But really, this is the house he lived in for fifty years with the love of his life. Yes, protecting Kevin from Muntz still matters, but of course he's going to focus on the house.
  • The Woobie:
    • It's very easy to feel sorry for Carl, especially at the end of the sequence chronicling his life with Ellie and their unfulfilled dreams.
    • Russell, when he was talking about his dad.
    • Dug is not accepted by the rest of the dogs (cone of shame! poor thing...).
    • Even Kevin the bird - remember when her leg was hurt? They all need a big hug!
      • Not to mention that there's an insane lunatic hunting her and putting her babies in danger with the intent to capture them and do who knows what else afterward.
