In the cinema of Claude Chabrol the bourgeoisie are distinctly lacking in charm, discreet or otherwise and none more so than Phillipe and Esther, the well-to-do couple at the centre of UNE PARTIE DE PLAISIR, who, at Phillipe's insistence, decide to have an open marriage but when Esther looks like she's falling for the first guy she sleeps with, Phillipe gets very jealous indeed.
The territory is, of course, typically Chabrolian but what makes this movie interesting as well as creepy and finally very unpleasant is that it would appear to explore the disintegrating marriage of its stars Paul Gegauff and Daniele Gegauff. Paul wrote the film in what appears to be a kind of exorcism though neither 'actor' rises above the one-dimensional. Nevertheless, Chabrol definitely embraces them treating them with more respect than either of them deserves. It may fit perfectly into Chabrol's world view of things but it's still a pretty hateful movie.
