Written by Alphonse Boudard, Le Mythomane had its origins in an episode of the 1979 series Histoires de voyous directed by Michel Wyn. The TV series tells the story of the daily lives of common petty thieves. This nice little gang consisted of Aunt Victoire, a “baroness” of the underhanded (Suzy Delair), Fernand, a gutsy rascal from the slums (Jacques Balutin) and Norbert Beaufumé (Francis Perrin), a petulant con artist whose pathological lying has driven him to maintaining two separate families.
