Continuity mistake: Tintin has a black and red striped tie as he and Snowy are walking. The tie becomes a black and brown striped tie by the time he returns to the apartment. (00:01:40)
Continuity mistake: Tintin arrives at the observatory with a green shirt. But by the time he finds the telescope, he suddenly has a yellow shirt. Then as Tintin walks back to the apartment, he has the green shirt again. (00:02:25 - 00:02:55)
Audio problem: When Tintin first sees the telescope, he says "What?" His mouth is out-of-sync when he says this. (00:02:50)
Revealing mistake: After Tintin exits the observatory, there is a shot showing us the meteoroid in the sky. In this shot, stars are visible through it. (00:04:40)
Continuity mistake: A tyre explodes and the remains go all around Tintin. But by the time the earthquake begins, nearly 80% of the burst tyre remains have vanished. (00:05:25)
Revealing mistake: During the earthquake, Tintin leaps onto a lamp post and the ground starts to rise. The inside of his mouth is green as this happens. (00:05:50)
Continuity mistake: When Tintin wakes up, night is visible outside of the window. As the camera pans around the room, showing everything all cracked and destroyed, daylight is visible outside one of the other windows. (00:06:30)
Revealing mistake: Professor Fossil places the results over a lamp and says "I have never seen such a formation before". As he says this, Tintin appears on screen. He never walks into shot, he just appears on the screen out of nowhere. (00:07:40)
Continuity mistake: The way the lamp in the observatory is bent changes between the shots where Professor Fossil says "Order 10 pounds of jelly beans" and the shot where he sings "We're going to the Arctic". (00:07:55 - 00:08:25)
Revealing mistake: The words on the article are not words. It's just letters mixed up into fake words. (00:08:40)
Other mistake: As Professor Fossil is on the radio, there is a shot showing us him on a newspaper. Look at the words on the article. All the words on the article are fading away. (00:08:40)
Continuity mistake: At the start of the boat scene, Tintin stands at the front of the ship and gets hit by a wave. In the front shot, the wave is seen going above his head. Yet when the camera is behind Tintin, the wave is suddenly below him. (00:09:15)
Audio problem: When Tintin says "Maybe we should go back inside" his mouth doesn't move. (00:09:20)
Continuity mistake: Haddock is handed the Peary's note with no crease in the paper. The shot cuts and the crease appears. (00:09:30)
Continuity mistake: After the Peary financier says "The Aurora will not reach the meteorite", the scene cuts back to the Aurora sailing through a storm. In this shot, the name "Aurora" is visible on the side of the side. Yet by the end of this scene, and the camera is in front of the boat, the name "Aurora" isn't visible on the front of the ship. (00:10:35 - 00:11:55)
Revealing mistake: When the scientists are eating their dinner and begin to get sea sick, one of them has a glass of wine. The wine slides along the table, yet the wine in the glass stays in a fixed position. (00:10:40)
Continuity mistake: As the boat sails through a storm, the boat's steering wheel is grey. The wheel becomes green as Haddock says "Shipwreckers!". (00:11:00 - 00:11:35)
Audio problem: The Aurora crashes into a ship. As Tintin and Haddock fall over, a glass related smashing sound is heard. There is no glass there to cause it. (00:11:30)
Revealing mistake: When the Peary financier scrunches up a piece of paper after finding out the Aurora failed to be sunk, his cigar is seen going through his lips. (00:12:05)
Revealing mistake: When Tintin emerges from his cabin, he starts yawning and stretches his arms. You'll notice that his arms go through the wall as he does this. (00:12:15)
Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
