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)
The Adventures of Tintin (1991)
1 deliberate mistake in Red Rackham's Treasure - chronological order
Starring: Christian Pellissier, Thierry Wermuth
The Seven Crystal Balls: Part 1 - S3-E3
Plot hole: Two clown performers finish their act and the curtain closes. Tintin and Haddock then talk for a bit about who will be performing before the musician, but within the span of merely just a few seconds, the next act is suddenly on stage and ready to perform. No way could the clowns have left the stage and the next act have been set up within that short of a time span. (00:04:45)
The Secret of the Unicorn: Part 1 - S1-E3
Tintin: He looks exactly like you.
Captain Haddock: Yes, he is good looking.
The Crab with the Golden Claws: Part 2 - S1-E2
Trivia: There is a mistake pointing out that the newspaper at the end is a flipped shot. If you flip it the right way round, you will see on the right hand side of the article the word "Spielberg" on one of the lines, a reference to director Steven Spielberg. Steven Spielberg went on to direct the Tintin movie Secret of the Unicorn in 2011. (00:43:35)
Tintin and the Picaros: Part 1 - S2-E8
Question: What did Calculus put in Haddock's soup? (00:13:45)
Chosen answer: It is a pill that makes alcohol taste disgusting.
