Dir/scr: Pen-ek Ratanaruang. Thai. 2007. 105 mins. Thai auteur Pen-ek Ratanaruang's most mature, measured film to date, Ploy offers a darkly poetic variation on the theme of The Seven Year Itch. Though its slow pacing demands a certain patience, the slow waltz of story, editing and camerawork goes beyond the surreal, open-ended ditherings of the director's last film, Invisible Waves, to deliver a solid dramatic punch and an unforced moral message.
