Other mistake: Tintin walks into Hector's apartment to give him his briefcase. An animation error occurs regarding his magnifying glass in the shot where Hector says "Just leave the mail on the table if you please."

The Calculus Affair: Part 1 - S1-E12
Other mistake: One of the villains says "With pleasure" after looking at Calculus and his radio. The other villain has a cigarette in his mouth. In this shot, you can see the cigarette has two ends to it. The edge of it cannot be ash because that would have been washed away in the rain. (00:03:15)
