death, and the use of firearms were toned down or removed completely. The use of text as a major part of the plot, such as the use of newspaper articles or writing on the wall, was largely cut so these scenes would not have to be reanimated for every language in which Tintin was aired. The radio and television are both used more frequently in the TV series to make up for the omission. Captain Haddock's penchant for whisky posed a problem for audience sensitivities. While the original books did not promote alcohol, they featured it heavily, with much humor based on drinking. However, in many countries where the producers hoped to sell the series, alcoholism was a sensitive issue. Therefore, international versions of the series had some alterations. "The Crab with the Golden Claws" is the only episode where Haddock's drinking is not significantly downplayed though it still played a pivotal role in several other episodes. In "Tintin in Tibet", Haddock is seen taking a sip from a flask of whisky to set up a scene in which Snowy, Tintin's dog, is tempted to lap up some spilled whisky and subsequently falls over a cliff. In "Tintin and the Picaros", Haddock is the only person taking wine with dinner, foreshadowing the use of Professor Calculus' tablets to "cure" the drunken Picaros. Haddock is also seen drinking in "The Calculus Affair" and "Explorers on the Moon", setting up the scene where he leaves the rocket in a drunken state. He does not hide the bottle in an astronomy book, as he does in the book, but keeps it in the refrigerator, making it less obvious for young viewers that it is alcohol. Throughout the books, Snowy is frequently seen to be "talking". It is understood that his voice is only heard through the fourth wall, but this verbal commentary is completely absent in the television series. The only time it is maintained is in the ending of "Flight 714", when he "speaks" with Tintin's voice. The character Jolyon Wagg only appeared in three stories ("The Calculus Affair," "The Seven Crystal Balls," and "Tintin and the Picaros") despite being in all but one installment of the book series. List of changes Smaller changes were made due to the necessity for simplification or audience requirements: "The Calculus Affair" In the book, the Syldavians tried snatching Professor Calculus from the Bordurians but were
