Adaptations
A semi-animated film based on the book was released in 1956, produced by the company Belvision, who would later produce the first Tintin television series, Herge's Adventures of Tintin. The film was produced by Karel Van Millegham and Anne-Marie Ullmann.
The 1990s Adventures of Tintin animated series changed the story. There is no 'Anchluss' aspect whatsoever, although it is clear that those scheming to steal the sceptre are based in a neighbouring state, as that is where they attempt to flee once they have it in their possession. Also, the Alembick twin who smokes becomes the bad one of the two.
