The Secret of the Unicorn: Part 2 - S1-E4
Character mistake: Mr. Silk has a collection of the wallets he has stolen and has sorted them on shelves by alphabetising them. Each shelf takes two letters of the alphabet, which is where the name of each owner's wallet would be placed on the shelf as shown by tags at the top of each shelf. Tintin finds Max Bird's wallet on one of the shelves and the shelf next to has a tag reading "Q-R." This implies that the shelf with Max Bird's wallet must have a tag reading "O-P" since O and P come before Q and R in the alphabet. Shouldn't Max Bird's wallet be located on a shelf with the letter "B" representing "Bird" or "M" representing "Max"? (00:42:20)
Red Rackham's Treasure - S1-E5
Character mistake: The "Oxygene" sign on the shark-submarine is missing the accent on the first E. (00:14:10)
Cigars of the Pharaoh: Part 2 - S1-E7
Character mistake: Just as the shot where Tintin yells "NOOOO!" ends, you can see he is smiling, even though he is locked in a mental hospital cell for doing nothing. (00:34:10)
The Calculus Affair: Part 2 - S1-E13
Character mistake: After reaching the border, Snowy finds an umbrella and Tintin states that it is Calculus's umbrella. It isn't Calculus's umbrella - Calculus's umbrella has a brown handle, and this one has a grey handle. (00:42:25)
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.
