Continuity mistake: When Haddock says "There they are" after the rescue, he is standing next to Professor Fossil and they are both standing at the end of the ship. As everyone starts cheering, they are standing somewhere near the middle of the ship and a scientist has suddenly appeared next to them. (00:20:30)
Continuity mistake: The pilot goes onto a raft and looks at Tintin at a 12 o'clock direction saying "I can't get any closer". In the next shot, he's looking at Tintin in a 3 o'clock direction. (00:19:20)
Continuity mistake: The huge apple that crushes the huge spider changes size between shots. (00:18:55)
Continuity mistake: When the huge apples fall off the tree, half of them are red and half of them are maroon. As the apples fall on the ground in the next shot, all of the apples are red. (00:18:20)
Continuity mistake: There is a shot of the meteorite and Tintin jumping onto it. In this shot he is approaching 4 meters away from the meteorite. Yet in the shot after a crew member of Peary yells "Pull, pull", Tintin is then seen approaching 4 meters to the meteorite a second time. (00:16:00)
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)
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)
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: 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)
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)
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)
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)
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)
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)
