I'd like to see Gravity, and A Touch of Sin. Can't find copies yet.
Meanwhile, on a whim, watched the Infernal Affairs movies again. Not as colourful as I remembered, but movie Cantonese is always fun anyway. (Du Zhan is so very obviously mainland China settings, I kinda remembered the Infernal Affairs movies as being very HK and, meh, the landscape is hidden in the background in all three, which is okay, and if you don't watch the subtitles you get lost fast.)
