Karl Zéro is the stage name of Marc Tellenne (born August 6, 1961 in Aix-les-Bains, Savoie), is a French writer, actor and filmmaker.

1979 Zéro met his later wife and mother of their three children Anne-Laure Chaptel (today's stage name: Daisy d'Errata) in the lyceum both were attending.

Subsequently, he started to work for the publications Métal Hurlant, Charlie Hebdo, Zoulou, and L'Écho des savanes, first as an artist and then as a story writer.

In 1986, Karl Zéro was hired by Europe 1 to host their show Géant Gratuit (Free Giant) with Doug Headline (son of Jean-Patrick Manchette).

In 1993 he successfully proposed adding a television news report parody called "Zerorama", "telling events of moral rearmament", in which he used a mode of presentation and tone inspired by newsreels of the Vichy regime under Philippe Pétain in order to satirise Édouard Balladur's government and the media supporting it.

In the show, he mixed classic news reports, usually filmed by the CAPA Agency, and sketches using video gags, in which his wife Daisy d'Errata frequently played a part.

Zéro, for his part, deplored Carles' wasting his time "beating down open doors", saying that "When one works for a television network, they're the ones who have the final cut".

In June 2003, with network consent and without naming them, he read aloud on the air the accusations of the serial killer Patrice Alègre (in the form of a letter which he had received from him) and of two former prostitutes that certain prominent people in Toulouse were involved in a sado-masochistic group which had covered up sexual assault, torture and murder.

The possible violation of journalistic ethics, frequent mentions of Zéro and Canal + in publicity about the accusations, and resulting political pressure contributed to the termination of his contract for Le Vrai Journal in June 2006.
