On a marché sur la Lune
Phostle was to return in "Destination Moon" and "Explorers on the Moon" as a villain, but that early draft by Bernard Heuvelmans was abandoned by Hergé. On the earlier "Hergé's Adventures of Tintin", which was made from 1957 to 1964, he was replaced by Professor Calculus at the episode Star of Mystery (The Shooting Star).
