The film version of Haruki Murakami's best-selling novel, Norwegian Wood (ノルウェイの森) was first shown at the Venice Film Festival in September last year where it was nominated for the Golden Lion award. It then opened in Japan in December and has already opened in several other countries in Asia, Europe and elsewhere. However, it will finally officially open in the UK on March 11th, 2011.
You've probably already seen the trailer, but if you haven't yet, here is the official English-subtitled trailer. Thanks to Shellie at Layers of Thought for the link.
