Professor Calculus talks about inventing High Definition television six years before high definition television existed.
In most of the episodes the same man appears - blonde with a boney face. He is either a passer-by, an artist or he is involved in the storyline. This is a reference to Hergé.
In every episode, someone calls Tintin, "Young man".
"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 adaptations. "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.
