Wow! That was a great compilation! The shameful thing was that I didn't recognise a lot of the footage, but at least that means there's a lot of LCY stuff for me to sink my teeth into.
As a point of opinion, I also think it would be that Korean movie, but purely for stylistic reasons. I'm not sure whether that the shot of LCY at the end were all in black and white or if they were in colour and then greyscaled. But I think that the tones in that were more in line with Korean film-making, as in HK they seem to do this less often and usually opt for a colourised b&w effect like using shades of dark blue. Just my opinion though :P.
