El cetro de Ottokar
"King Ottokar's Sceptre" was the first of "The Adventures of Tintin" to be adapted for the animated series "Hergé's Adventures of Tintin". The series was created by Belgium's Belvision Studios in 1957, directed by Ray Goossens and written by Greg. The studio divided "King Ottokar's Sceptre" into six 5-minute black-and-white episodes that diverged from Hergé's original plot in many ways. It was also adapted into a 1991 episode of "The Adventures of Tintin" television series by French studio Ellipse and Canadian animation company Nelvana. The episode was directed by Stéphane Bernasconi, and Thierry Wermuth voiced the character of Tintin.
