Gorgeous, bronzed bodies on the beaches of France and a passionate romance between two French youths are reason enough to buy Come Undone, but this bittersweet film also has something poignant to say about the heartbreak of gay first love.  Eighteen-year-old Mathieu is vacationing at the beach with his family when he meets local teen Cédric (Stéphane Rideau, the object of affection in Wild Reeds).   After an extremely erotic kiss, the boys begin a hot and heavy affair, complete with skinny-dipping at night, nude dancing on the beach and intense lovemaking in the dunes.  Yet as Mathieu grapples with his sexuality and copes with his sick mother, absent father and annoying kid sister his bond with Cédric grows stronger until it bursts.  The film, directed and co-written by Sébastien Lifshitz (who was photographed by Karl Lagerfeld and profiled along with Elkaïm in the October 2001 issue of Interview Magazine) beautifully conveys Mathieus coming-of-age.  Both Elkaïm and Rideau are incredibly sexy leads and give remarkable performances as the affectionate teens.
