Numa Sadoul is a French writer, actor, and director, who has been a resident of France since 1966. As a student, Sadoul interviewed and befriended the famous Belgian cartoonist Hergé, famous for his Adventures of Tintin—an unexpected coup, as Hergé gave few interviews. The interviews were recorded on 14 hours of tape, and, after heavy editing by Hergé, released as a book: Tintin et moi / entretiens avec Hergé, in 1975. In 2003, the book was used as a basis for a documentary filmTintin and I, directed by Anders Østergaard. Sadoul has also published interviews with other leading Franco-Belgian comics artists, such as André Franquin, Jacques Tardi, Philippe Vuillemin, as well as books on Gotlib and Uderzo. Particularly noteworthy are his interview books with Frenchcomic artistJean "Mœbius" Giraud. Sadoul followed the career of Giraud closely from the mid 1970s onward until the latter's death in 2012, conducting extensive interviews with the artist throughout this period of time, which resulted in three consecutive interview books, Mister Mœbius et Docteur Gir, Mœbius: Entretiens avec Numa Sadoul, and Docteur Mœbius et Mister Gir, the latter two being each an updated and expanded version of the previous one. Excepting parts of the first book, none of the later interviews had seen prior magazine publication, be it in part or in whole. The last version therefore was an posthumous account where the last two decades of Giraud's life were concerned. As a kid, Sadoul was as fascinated by the stage as he was by comics. At the age of 23, he set up his own theater company in Rouen. Since then, as head of his troupe Les Enfants Terribles, he has filled every position connected with the stage: actor, director, author, stage manager, and drama teacher, in addition to head of a theater school for children and teens in a town on the French Riviera. Later, in the 1960s and 1970s, his passion for the stage combined with that for vocal music would lead Sadoul to become an opera critic, before integrating the trade in 1977 as a full-blown opera director; he has been invited to produce operas and plays alike on the most prestigious stages in France, from Lille and Bordeaux to Nice and Marseille. This part of his life is recounted in the 2016 book "Forty Years at the Opera, Egodictionnaire de l'art lyrique".
