chevetIf I am wel informed, the project called Le ThermoZéro is a project for a Tintin book and not for a Jo, Zette & Jocko adventure.
No, Chevet, it is both, but you are not the first person I have had trouble convincing of this!
Thanks for the link to the Greg page, it is very interesting: it is particularly so because it points out that while Hergé could not work with the script, he did in fact think that it was good (a crucial point missed by many, who assume it was dropped fo reasons of quality
What it misses is what he did with it next.
As I explained in the conference article quoted above, once Hergé had given up Greg's script for a Tintin
book, he passed it to Bob De Moor to transform the same basic scenario into a JZ&J
This actually isn't in itself news, as in their biography
of Bob de Moor (Bob de Moor. 40 ans de bandes dessinées, 35 ans aux côtés d'Hergé
, [Lombard, 1986]), Bernard Tordeur and Pierre-Yves Bourdil published some of Bob's notes and sketches for the JZ&J
news was that the JZ&J
book which Bob developed was substantially complete, and the possibility was that it could be published. Apparently nobody had ever asked that question of him before...
Hope this clarifies things for you - I can really recommend the de Moor biography, if you want a look behind the scenes at his work with Hergé, and his solo career.
