A contemporary “Tristan and Isolde,” L'Eternel Retour, written by Jean Cocteau and directed by Jean Delannoy (Pontcarral), was an enormous commercial success during the worst days of the German Occupation of France; less so after the war, when many foreign critics found it disquietingly morbid. The “eternal” story of a friendship between two men and the love of a woman is set in a castle within whose walls resides a dwarf whose role it is to thwart any intimacy between the would-be lovers. As always, Cocteau has created a contemporary classic, beautifully photographed by Roger Hubert.
