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, passed away of old age just a few months later.
  • 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.
  • 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 paranoic... it's so tragic... Of course, murdering or even attempting to murder innocent people because he thought they would take his bird away (his biggest fan and a child, no less) makes him a bit of a monster.
  • Magnum Opus: Perhaps not to the extent of Wall-E or the Toy Story films, but there are quite a few who hold this up as one of Pixar's finest films. At the very least, there are those who will cite the film's early montage as the best individual scene of Pixar's tenure.
  • Memetic Mutation:
  • 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.
  • Sweet Dreams Fuel: The ending credits, with little tokens of Russell and Carl's friendship and lots of puppies.
  • 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.
