Une vieille maîtresse (2007), adapted and directed by Catherine Breillat, was shown in the U.S. with the title, "The Last Mistress." This is a period film, set in early 19th-century France.
The basic plot is a love triangle--Fu'ad Ait Aattou plays the young aristocrat, Ryno de Marigny, who wants to marry the virtuous young woman, Hermangarde, played by the elegant Roxane Mesquida. Asia Argento plays Vellini, a highly sophisticated courtesan, with whom de Marigny has been having an affair for ten years.
The film is filled with beautiful women and lots of sex, but not much else. de Marigny doesn't seem all that desirable or interesting to me, and I didn't buy the plot line that Vellini simply couldn't let him out of her life. It's not that prostitutes can't fall in love, but it struck me as unlikely that this prostitute would fall in love--and stay in love--with this client.
We are supposed to understand that sexual values and attitudes are shifting at this time, and women are becoming liberated from the assumption that they can only be desired, but can't have desires themselves. Maybe so, but I think that justification was tacked on to a film whose raison d'etre is the display of lovely female bodies.
This movie was shown at the excellent Rochester High Falls International Film Festival. Most of the action takes place in drawing rooms and bedrooms, so the film will work well on DVD.
