François Ozon's perfectly cast Swimming Pool pits a 50-something British mystery author, played by Charlotte Rampling, against her publisher's 20-something daughter, played by Ludivine Sagnier. They both end up in the publisher's remote house in France, each expecting to be there alone. The writer was hoping to find a quiet spot to work on her new novel, and the daughter was planning to party late and bring home a different man every night, which she proceeds to do. The movie is told from the author's point of view, but Ozon's camera seems to like the two characters equally, which is a nice setup that doesn't really have a worthy payoff. Where it goes depends on how you want to see the ambiguous third act. It's either a mystery thriller with holes so big that Rampling's character would have been embarrassed to write them: thin motives, contrived twists, and eleventh-hour revelations that require us to pretend some earlier events didn't happen (we'd need to assume the publisher never received Rampling's angry calls about his daughter being at his house when it was supposed to be vacant). Or, more probably, it's a psychological drama in which we wonder how much is real and how much is just a part of the novel in progress.
I like movies that blend the mental and physical as a way to get into a character's head, especially when we're not always told which is which — Scorsese's King of Comedy and Kubrick's Eyes Wide Shut come to mind — but they lose me if that technique becomes one of the movie's focal points or if it no longer serves the characters but instead produces fireworks on its own. In Swimming Pool, the appearance of the girl parallels the writer's feeling that she has arrived somewhere fresh with her new book, that she has found some old spark, but I wish the movie had further explored the connections between the two women — and therefore explored the author's inner life — rather than skimming the surface. Showing us the novel that this character writes when she's on a roll should tell us something about her, but all we get are obvious observations about Rampling being a mother figure or recalling her youth in swingin' London, both dead ends. Sagnier is very sexy, and Ozon creates an atmosphere that is both soothing and unsettling, but without its attractive actresses and ambiance, the movie would suffer, of course, but would also be quite empty when it didn't need to be.
