Captain Haddock the Picaros", when Professor Calculus 'cures' him of his taste for alcohol. In the adventure "Secret of the Unicorn" (and continuing in "Red Rackham's Treasure") he and Tintin travel to find a pirate's treasure captured by his ancestor, Sir Francis Haddock (François de Hadoque in French). With newfound wealth and regaining his ancestral home Marlinspike Hall, Captain Haddock becomes a socialite; riding a horse, wearing a monocle, and sitting in a theatre box seat ("The Seven Crystal Balls"). He then evolves to become genuinely heroic, volunteering to sacrifice his life to save Tintin's own in the pivotal "Tintin in Tibet".
Tintin and the Picaros television series. Directed by Stéphane Bernasconi, the series has been praised for being "generally faithful", with compositions having been actually directly taken from the panels in the original comic book. Many fans felt it was out of character for Tintin in the book to refuse to go to South America. In the television episode, Tintin is all for rescuing his friends and goes with Haddock and Calculus early in the adventure. In the original comic, Tintin wore bell-bottoms throughout the book, which was in contrast with the plus-fours he had always worn previously. In the episode, his plus-fours have returned.
