"Tintin in the Land of the Soviets", "Tintin in the Congo" and "Tintin and the Alpha Art" were the only books to not be given episode adoptions. "Land of the Soviets" book wasn't redrawn to resemble the other books and was highly discriminating for the country of Russia. "The Congo" book had racial issues and animal cruelty. Finally "The Alpha Art" book was the only one to be incomplete due to the death of Herge.
A fan in England posted videos online, featuring overdubbed clips from this series, in which the characters use profanity-laced dialogue. The viral clips can be found under the title "Teesside Tintin".
