orologio en Altadefinizione. Luc Lagier puts Alain Resnais' film back in its historical context and in the filmmaker's biography. He tells the story, then the development of what was originally intended to be a short documentary film and which turned into an unusual allegory. Composed of fascinating archives, including notably the correspondence between Duras and Resnais, this analysis of 'Hiroshima mon amour' manages to put the film in perspective while detaching itself from it. A rare and captivating work.
