In the L'étrange enlèvement du petit Bruno, the French adaptation of Agatha Christie's The Adventure of Johnnie Waverly for the TV series Les Petits Meurtres d'Agatha Christie, Bruno Zennefort is the parallel character of Johnnie Waverly in the original story. He is the son of Hadrien Debaer and novelist Eloïse Zennefort. Like in the original, he is kidnapped and later released. In the original, Johnnie's toy dog was an important clue. In this case, a pike dropped from one of his toy soldiers served the same purpose for commissaire Laurence.
As the son of Hadrien Debaer, Bruno really should be Bruno Debaer but the end credits clearly list him as Bruno Zennefort. Bruno is portrayed by James Leblanc.
