Few, if any, changed fashion like Yves Saint-Laurent did in the 20th century. His legacy upon his death in 2008 was more than his contributions to fashion; it included one of the great collections of art in the world - and the man he built an empire with. Pierre Thoretton's directorial debut follows the indelible icon through the eyes of lifetime love and business partner Pierre Berge from his early days as a design prodigy for Christian Dior through his decades as the face of a fashion empire. Framed by the auction of their priceless collection, this touching documentary captures the complete life of the man behind the monogram, whose private struggles with depression and substance abuse often underscored his triumphs and innovations. L'Amour Fou never ceases to show the beautiful extravagance and celebrated style of Saint-Laurent in his work and his life.
