Note: Some sources claim that this was a pseudonym used by Frédéric Dard. This claim has been rejected by Dard's family. In addition, the BnF authorship notice (BNF cb11920596h) shows Marcel G. Prêtre as a separate person. As per BnF, he was an author and screenwriter who also wrote as "Marcel C. Preaster" and, with Marcus Waeber, under the collective pseudonym "François Chabrey".
