James Ivory collaborated with his usual screenwriter, Ruth Prawer Jhabvala, in adapting Diane Johnson’s witty novel about contemporary Americans in Paris, and the result is close to the original in spirit even if it differs in some specifics. Kate Hudson plays a footloose Santa Barbaran who arrives in Paris to visit her older sister (Naomi Watts), a poet whose painter husband (Melvil Poupaud) is leaving her, and winds up having an affair with a TV pundit and former diplomat roughly three times her age (Thierry Lhermitte). As in other Ivory-Jhabvala adaptations, ritzy consumerism is very much on display, but what makes this better than most is Johnson’s amused admiration for nearly all her characters, regardless of nationality. (One exception is a crazed American entertainment lawyer, played by Matthew Modine and handled awkwardly throughout.) Especially fine are Glenn Close as a stand-in for Mary McCarthy and Stephen Fry as an art appraiser from Christie’s. With Jean-Marc Barr and Leslie Caron. 115 min.
