The Secret of the Unicorn: Part 1 - S1-E3
Other mistake: When Tintin discovers the scroll under his drawers, he begins reading the French words on the scroll in English. He starts reading out by saying "Three brothers joined." This sentence translated into French would be "Trois freres rejoint." However, this is not what is shown on the scroll. The sentence shown on the scroll appears to be "Trois freres unys." (00:09:20)
The Secret of the Unicorn: Part 1 - S1-E3
Other mistake: After discovering the scroll, Tintin begins reading it out. The words on the paper, the words Tintin is saying, and where Tintin's eyes move as he read the paper don't seem to match up. Tintin first says "Three brothers joined", which covers the first half of the line, but the next shot then shows his eyes reading at the very end of the line. Tintin then says "Three unicorns in company sailing in the moon day sun will speak", and his eyes are then reading across the second line, but the start of the sentence is shown on the second half of the first line of the scroll. (00:09:20)
The Secret of the Unicorn: Part 1 - S1-E3
Other mistake: When Tintin is reading out the scroll, the scroll is in French and Tintin is reading it out in English. The first word on the second line is "conserve", which means "preserve" in English. The word "preserve" however is never spoken when Tintin reads out the scroll. (00:09:20)
The Secret of the Unicorn: Part 1 - S1-E3
Continuity mistake: Tintin runs up to Captain Haddock's apartment door and begins knocking on the door. When Tintin begins knocking, the colour of Haddock's door is brown. In the next shot, the colour of the door is suddenly red. Then in the shot after that, the colour of the door is suddenly back to brown again. (00:10:25)
The Secret of the Unicorn: Part 1 - S1-E3
Other mistake: When Tintin attempts to break down Captain Haddock's door, there is no key lock hole on the front of the door, but there is a key lock hole on the back of the door. (00:10:50)
The Secret of the Unicorn: Part 1 - S1-E3
Audio problem: When Captain Haddock's neighbour says "Is everything all right?" her mouth is wide open but doesn't move. (00:10:55)
The Secret of the Unicorn: Part 1 - S1-E3
Continuity mistake: When Captain Haddock shows Tintin the journal that belonged to Sir Francis Haddock, it's brown. Much later on in the episode, after Haddock has finished telling Tintin about the story of Francis Haddock, the journal is suddenly much lighter. (00:11:40 - 00:19:45)
The Secret of the Unicorn: Part 1 - S1-E3
Other mistake: When Haddock stabs the cushion on the couch, the sword goes right through the cushion, but no damage is made to the couch. (00:15:25)
The Secret of the Unicorn: Part 1 - S1-E3
Continuity mistake: When the pirates are partying, one of them throws a wine bottle towards the tied up Francis Haddock. One of his hands is shown tied and wrapped in ropes. The shot then switches to a close-up of his hand, which is now wrapped around the ropes tying his body to the mast, and not the other ropes shown a second ago. (00:17:10)
The Secret of the Unicorn: Part 1 - S1-E3
Deliberate mistake: After Francis Haddock kills Red Rackham, he lights a fuse to the explosives. The fuse that was lit is only a foot long, yet he is somehow able to climb out the ship without anyone noticing, get into a boat and swim all the way to land before it explodes. At a foot long it would have exploded in 10 - 15 seconds, all of that would taken at least 10 minutes. (00:18:45)
The Secret of the Unicorn: Part 1 - S1-E3
Revealing mistake: Francis Haddock lowers himself from the ropes to the lifeboat below. He steps foot inside the boat, but the bottom of his legs and his feet are still perfectly visible when they should have been covered up by the boat. This error in the animation makes the boat appear as if the boat is missing one of its sides. (00:18:50)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: Tintin, Haddock and Snowy are walking down the street and Haddock says he's going to be rich and tosses his hat in the air. There is a lamppost right next to Tintin. A man then opens his window, telling Haddock to keep the noise down and Tintin is suddenly standing about a foot away from the post. (00:26:20)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: When Tintin, Haddock and Snowy are walking down the street, they stop walking for a moment next to a lamppost. The shadow of the post is first cast across the building next to it. About two shots afterwards, the shadow is suddenly cast on the sidewalk directly in front of it. (00:26:20)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: When Haddock throws his hat in the air, there is a lamp post located next to Tintin and it is a light blue colour. A couple of shots later, the lamp post is suddenly a much darker turquoise colour. (00:26:20)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: The mast on the Unicorn model Sakharine has changed color when Tintin and Haddock find it, from beige to grey. (00:27:40)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: Sakharine is lying on the floor when they find him presumably dead. But when Thomson and Thompson run out of the room, Sakharine has disappeared. (00:28:20)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: When Captain Haddock approaches Thomson and Thompson, their hair is all messy. About 2 shots later, their hair is neatly combed. (00:28:35)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: When Sakharine wakes up, his door goes from fully open to nearly closed in the shots of Tintin without any time to close the door. (00:29:10)
The Secret of the Unicorn: Part 2 - S1-E4
Continuity mistake: When Sakharine wakes up, Tintin runs to him and the detectives trip up. They are next to the door. In the next shot, we can see the door, but none of the detectives. (00:29:10)
The Secret of the Unicorn: Part 2 - S1-E4
Audio problem: Tintin figures out Sakharine was knocked out by being chloroformed and the detectives say "Oh". Neither of the detectives' lips move when they say it. (00:29:20)
Chosen answer: It is a pill that makes alcohol taste disgusting.
