Le Temple du Soleil
"The Seven Crystal Balls" was a commercial success and was published in book form by Casterman shortly after its conclusion. Hergé concluded the arc begun in this story with "Prisoners of the Sun", while the series itself became a defining part of the Franco-Belgian comics tradition. Critics have ranked "The Seven Crystal Balls" as one of the best "Adventures of Tintin", describing it as the most frightening instalment in the series. The story was adapted for the 1969 Belvision film "Tintin and the Temple of the Sun", the 1991 Ellipse/Nelvana animated series "The Adventures of Tintin", the 1992-3 BBC Radio 5 dramatisation of the "Adventures", the 1997 video game "Prisoners of the Sun", and a 2001 musical in Dutch and French versions.
