Red Rackham's Treasure - S1-E5
Other mistake: Professor Calculus brings the parts for two shark submarines (he stated in the scene prior he would bring two) to the docks in two separate crates. The crates he uses to hold the submarine parts in would not big enough to hold the entirety of the submarine. The crates shown are only a couple of feet wide and even smaller in height, but the shark submarines shown in the episode are much larger than the overall size of the crate. (00:06:50)

Other mistake: When Haddock fires at the shark, he is firing to the right, but the shark is directly in front of him. The bullet is still heard hitting the shark anyway. (00:13:00)
Red Rackham's Treasure - S1-E5
Other mistake: When Haddock walks over to Tintin whilst the boat is on the docks, a crate is lifted. The X that is written on the crate disappears from shot when the crate is lifted, revealing it was not animated in each frame of the shot. (00:06:45)

Other mistake: The guy looking at George and Bill in the cafe has red eyes. (00:04:05)
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.
