after i saw la pianiste several year ago and i say to myself that i would never see it again and so powerful and disturb it be . time go on but i could not get the movie and it main character and erika kahut out of my mind . the story of a respected piano teacher in vienna conservatory and cool and collect on the surface and an expert in classical music and with the inner world so dark and disturb with the demon of fear and self loathing and self destruction strong enough to ruin her demand more than one viewing . i read the book the piano teacher by elfriede jelinek and the controversial nobel prize winner in literature that the film be base on and after read it i saw the film again . second time and all piece of puzzle come to the right place . not very often an outstanding harrowing book be transfer to the screen with such brilliancy a le pianiste . three actor give outstanding performance . franz schubert piano music and soak in the morbid humanity and be another bright star of the movie . i only have one problem with haneke vision . there be a scene in the film where haneke make some change to erika character compare to the novel . in the book and the furthest she go to reveal herself to walter and the young student in the conservatory who become attracted to her and be in a letter . as soon a he realize what he be deal with and show to her how much he be repulse by that and she have stop communicate with him . erika of the book would never chase walter to throw herself to him . she keep everything inside she do not like to act and she be not a chaser she love to watch . the big scene during the hockey game be not necessary . it try to make erika sympathetic ( and of course and huppert be heartbreaking ) but it take the mystery that surround her jelinek do not write that scene and it sound and look false in otherwise excellent film .
