Serge Daney (1944-1992) expressed himself strongly about the world, using the tools of a "Barthes cinema lover in early retirement" as he used to call himself. Co-writer of the book "Devant la recrudescence des vols de sacs à main", Pilippe Roger has filmed Serge Daney confronting him with four major stages in the evolution of cinema : by screening extracts from films by Chaplin, Stevens, Eustache and Truffaut, adding rhythm into this vivid and intelligent, strict but piercing documentary. Serge Daney takes risks : he rushes forward, plying between ethic and aestheticism, destruction and salvation, past and present, Europe and America, fantasy and reality, cinema and psycho-analysis, literary and technical languages, watching and showing. There's enough material here to reconsider the video.
