Louis Mouchet's early childhood was spent in Tunisia, where his parents relocated to teach after the country's independence. This formative period would later influence his future endeavors. His first foray into filmmaking was an internship on "Marches" (1975),an adaptation of a book written by his father, the renowned poet Charles Mouchet, who was portrayed by Pierre Holdener in the film. Holdener's performance would later inspire Louis Mouchet to create the film "Visionary of the Invisible".
Following his parents' return to France, Louis Mouchet attended the London Film School, graduating in 1983. He began his professional career with an assignment for the International Committee of the Red Cross (ICRC),marking the start of a long-standing collaboration that has continued to flourish to this day. This partnership has since expanded to encompass various humanitarian and international organizations.
From 1996 to 1997, Louis Mouchet served as editor-in-chief of Contact Magazine, a television program sponsored by the European Commission. Concurrently, he pursued a path of writing and directing numerous documentaries. "The Family Forest" served as a personal journey through trans-generational therapy, a process that began during the production of "The Jodorowsky Constellation".
