THE KEY (1983)
TINTO BRASS
Plot
A spicy adaptation of a work by Japanese author Junichiro Tanizaki transposed to pre-war Venice. Frank trys to loosen the inhibitions of his young wife by writing his erotic fantasies in his diary, she has an affair with a younger man, and then she and Frank really get it on! Lots of naked Stefania Sandrelli; mainly made in English but with a few bits dubbed from Italian.
