This is only my second Bunel film (The Discreet Charm of the Bourgeoisie), and I am fascinated with the way he portrays the upper crust. here we have an odd family with some strange habits. Didn't you always think they were like that. It's the old joke about how you can determine class bu how two couples sit in a car. Lower class - men in front and women in the back; middle class husbands and wives sit together; upper class husbands sit with the other's wife.
Show fetishes, randy husbands, cold wives, rape and murder are all here amidst a fascist France. They are always going on about the republicans, ours would fit right in with the anti-semitism and xenophobia.
Among all this is the classic acting of Jeanne Moreau, a classy chambermaid, who is even willing to marry a fascist to prove him guilty of murder and rape. In the end, she turns out to be just an opportunist.
It would probably be more enjoyable knowing more about 1930s France, but it was still a classic.
