Other mistake: One of the villains says "With pleasure" after looking at Calculus and his radio. The other villain has a cigarette in his mouth. In this shot, you can see the cigarette has two ends to it. The edge of it cannot be ash because that would have been washed away in the rain. (00:03:15)

Other mistake: When the taxi gets hit, the number plate reads "GE 7051" on the back of the car, but when the taxi falls into the water, the number plate reads "GE 7054" on the front of the car. The number plate should be the same on both ends. (00:14:55)
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.
