Cigars of the Pharaoh: Part 1 - S1-E6
Revealing mistake: On the boat, Tintin chases after a paper. There is a shot of a man being handed a drink and the paper continues to blow away. Keep an eye on the paper and you will see it disappears before it reaches the end of the screen. (00:01:35)
Red Rackham's Treasure - S1-E5
Revealing mistake: In the shot where Tintin drives past the Unicorn and a shark appears, a white speck is visible to the left of screen. It disappears from shot when the shark arrives in shot. (00:14:05)
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.
