South Korean filmmaker Kim Ki-duk (3-Iron, Spring, Summer, Fall, Winter . . . and Spring) makes movies that can be viscerally shocking and intellectually challenging; they’re rarely as soporific and reductive as this 2008 tale of the supernatural. A Japanese calligrapher in Seoul (Jo Odagiri) discovers that his nightmares about his ex-girlfriend and her new lover are being acted out by a pretty sleepwalker (Lee Na-yeong); hoping to keep the young woman out of harm’s way, he moves in with her and coordinates their sleep schedules so that his dreams won’t influence her unconscious. Once Kim establishes this conceit, though, he does little with it, stumbling to a feeble conclusion in which a butterfly (a Korean symbol for marital bliss) provides ironic commentary on the fates of his hapless characters. In Japanese and Korean with subtitles. 93 min.
