Red Rackham's Treasure - S1-E5
Continuity mistake: Calculus walks into the apartment to talk with Tintin and Haddock. When he starts talking, his back is straight and sitting upwards. The shot cuts and he is suddenly sitting slightly forwards with his head also pointing forwards. Then in the following shot after that, he is suddenly sitting with his back straight and is sitting upwards again. (00:05:05)
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)
Red Rackham's Treasure - S1-E5
Continuity mistake: When Calculus arrives at the docks to demonstrate the shark submarines, there are images of the submarines shown on each crate. There is no crease shown on the image on the top crate and there is a crease on the image on the bottom crate. A couple of seconds later, Haddock draws an X on the image shown on the top crate and the image shown on the top crate now suddenly has a crease on it. (00:06:50)

Continuity mistake: When Tintin and Haddock discover Calculus had been sleeping in one of the lifeboats, he wakes up and tells him he slept rather badly last night.

Continuity mistake: Whilst Tintin, Haddock and the detectives are on their way back from Francis Haddock's island in the boat, there is a Sirius logo on the front of it.

Red Rackham's Treasure - S1-E5
Deliberate mistake: Haddock draws an X on the shark image of Calculus' box with a pencil. This was done as a visual gag, though the X mark is far too thick for the pencil that Haddock was using. (00:07:00)
Red Rackham's Treasure - S1-E5
Continuity mistake: When Haddock realises Calculus placed the shark submarines on the ship, he goes outside to find him and slips on a small puddle of booze. About two shots after this, the size of the puddle is suddenly much larger. (00:09:20)
Red Rackham's Treasure - S1-E5
Audio problem: When Haddock tells Tintin that somebody on the ship is stealing food, Tintin says "Snowy?" When he says the line, his mouth opens, but his lips don't make any further movement as he is saying the line. (00:08:25)
Red Rackham's Treasure - S1-E5

Audio problem: Haddock and Tintin shout "Calculus" when they find out he is on the ship. As they say it, Tintin is heard saying it but his mouth is wide open and wouldn't be able to say it whilst open. (00:09:35)
Chosen answer: It is a pill that makes alcohol taste disgusting.
