Harry Thompson, author of "Tintin: Hergé and his creation", writes that the introduction of this large and luxurious country house was "to provide a suitable ancestral home for Tintin and himself to move into."

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.
