- When Tintin buys the Unicorn model from the merchant at a discounted price, someone tries to buy it from him for double what he spent on it. What makes it heartwarming is that he refuses, even when another man approaches him with an even more tempting offer. Tintin makes it clear to both men that he didn't buy the ship just to make a profit, and he says so very politely.
- Haddock's motivational speech to Tintin during his Heroic BSoD stage:Captain Haddock: I thought you were an optimist.
Tintin: You were wrong, weren't you? Im a realist.
Captain Haddock: Ah, it's just another name for a quitter.
Tintin: You can call me what you like. Don't you get it? We failed.
Captain Haddock: Failed. There are plenty of others willing to call you a failure. A fool. A loser. A hopeless souse. Don't you ever say it of yourself! You send out the wrong signal, that is what people pick up. Don't you understand? You care about something, you fight for it. You hit a wall, you push through it. There's something you need to know about failure, Tintin... You can never let it defeat you.
- Hergé's Creator Cameo at the Belgian marketplace. What makes it even sweeter is that after the intro credits, he's the first person you see in the film.Hergé: I have to say, your face is familiar. Have I drawn you before?
- After the chase in Bagghar, Tintin is wrestling Sahkarine's bird for the last scroll. Sahkarine threatens to drown Haddock and Snowy if Tintin doesn't let the bird go. Sahkarine drops Haddock and Snowy into the water, and Tintin goes after them instead of getting the scrolls first. Aww.
- This one's more heartwarming after a trip to the fridge. During the scene where Haddock has a flashback to Sir Francis fighting off pirates on the Unicorn, Sir Francis lights the magazine to blow the ship up. Haddock, thinking he is Sir Francis on the ship, grabs Tintin and tosses him out the window so that he's not killed when the "ship" blows up. Here's the heartwarming part: Sir Francis was by himself and only had enemies around, so logically, Haddock should have just jumped from the window himself and left all the "pirates" behind. Even in the middle of a flashback to a previous life, Haddock still has the presence of mind to make sure his friend was safe.
