Director Wong Kar Wai's semi-sequel to 2000's luminous In the Mood for Love takes off in a myriad of unusual and unexpected directions. Tony Leung more or less reprises his wounded romantic role from In the Mood for Love. He again takes up residence in a Casablancaish Hong Kong hotel where he meets a series of women, including a prostitute, the hotel owner's daughter and a high-class call girl (Zhang Ziyi from Hero)--all of whom filter though room 2046. He also starts to pen a series of futuristic stories--set, of course, in the year 2046. This chilly Kubrickesque future plays out as either a moody metaphor for our protagonist's life or some sort of futuristic "memory" of things past. Frankly, the plot is pretty hard to work out. But that isn't Wong's concentration here: It's all about image, tone and composition. In that respect, this romantic mystery is a haunting visual masterpiece. In Cantonese, Japanese and Mandarin with English subtitles. 129 minutes R.
