This melodrama is sleek and elegant if sometimes short on motivation. Updated version of an Emile Zola 19th-century novel [La curee] deals with a rich financier married to a very young woman (Jane Fonda). He also has a 22-year-old son (Peter McEnery). Love blossoms between this son and the young wife.Director Roger Vadim has a glossy style that shows the aimless life of the bored wife and the drifting son that finally results in love only to be throttled by his weakness which ends in the woman’s breakdown. McEnery is effective as the weak son while Michel Piccoli does not have the right sort of role to be able to limn a strong and overpowering father figure to overcome love and desired freedom.
