I am sure that anyone interested in the production details about the filming of this striking film from the late 70s will find a lot of information on the Internet, so I will focus on the essentially cinematic aspect, if you can call it that, of a unorthodox film with overtones of Buñuelian surrealism (The discreet charm of the bourgeoisie).
The room of a restaurant (a real one, by the way, not a set) serves to offer on a silver platter any à la carte sexual demand that customers require from their waiters, to the rhythm of a waltz. Each with their own demands, the mistakes of the female servants are paid for with fellatio to the head waiter. All very strange and at the same time so magnetic.
I haven't really found a specific plot thread to intertwine the different scenes, but the majestic setting and the appearance of a spectacular Annette Haven seem like two essential arguments for reviewing this title once again. And then another.
P. S.- The sensational oral study that actress C. J. Laing performs on one of the waiters, and which ends with one of the most morbid facial discharges that I can remember, will be etched in your retina in perpetuity. You are welcome.
