For forty years, a filmmaker has obsessively collected magazine covers, articles, and photographs of Isabelle Adjani, carefully cutting and pasting them into large notebooks — now reaching volume 42. Les Cahiers d’Adjani transforms this lifelong fan devotion into a cinematic exploration of memory, obsession, and the passage of time. As the director finally dares to turn his camera toward his own secret archive, the film unfolds as both an intimate self-portrait and a reflection on fame, desire, and the fragile bond between artist and admirer. Through these meticulously crafted “cahiers,” it becomes a story of objects, collectors, family, and the strange ways in which a life can be shared with a star through images.
