I am not sure that I can reach the intellectual heights of some the previous reviews - however, I found it an intensely moving film. Wonderful acting all around - but in particular, Tony Leung (as always), Zhang Ziyi and Faye Wong really hold the heart of the film. You do not need to have seen the previous film to enjoy this, but it will deepen your understanding - the repeated imagery from In the Mood for Love (a hand on a balustrade, a figure against a wall, cavities for telling secrets into) was one of the key pleasures of the film for me. The film looks wonderful - both the parts set in the 60s and the futuristic segments - and will reward multiple viewings. Put simply, one of my favourite films of the last few years.
