Only people who have not read Leblanc's absorbing novels can enjoy such rubbish."L'Aiguille Creuse" ,notably ,is a disaster,with appalling music and a screenplay which destroys all the magic and the emotion of the story which made Etretat town a legend.Georges Descrières is not that much a good Lupin.Leblanc's novels displayed a sense of humor ,but here ,we verge on parody.
Lupin's fans avoid these 1971 films and do try to get "l'Ile aux Trente Cercueils" " (where Lupin does not appear but which captured Leblanc's suspenseful atmosphere ) and "Lupin joue et perd" (from "813" ) with the marvelous Jean-Claude Brialy.
