Marius is all about TV shows. After graduating from Montaigu's Audiovisual Program, he honed his skills at Canal+ (e.g. producing the "Journal du Hard" for ten years). Over the next 20 years, all channels have sought his services for the production of multi-camera interview sets. Canal+ frequently relies on his services as well for the creation of their event teasers (such as "Bureau des Légendes," "Versailles," "Baron noir," and more). Marius has also written and directed several documentaries about cinema.
