 In his memoirs , Władysław Szpilman also compared himself to Crusoe and , like Fogelman , emphasized the isolation and hopelessness which characterized the Warsaw Crusoes . Szpilman 's memoir served as a basis for a screenplay , written as early as 1945 by the Polish writers Jerzy Andrzejewski and Czesław Miłosz , entitled Robinson of Warsaw . The movie that was eventually filmed , Miasto Nieujarzmione ( " Unyoked city " ) , was heavily censored by the communist authorities , and its original theme changed to such an extent that Miłosz requested his name be removed from the film 's credits . The experience with the film contributed to Miłosz 's disillusionment with cinema as an artistic medium .
