Specs on the disc via DVDTimes:
http://www.dvdtimes.co.uk/content.php?contentid=55675Extras look very good (ported from the Korean SE), especially for a foreign movie... This almost makes me regret on picking up the HK disc so soon. I might buy this again since I like the movie quite a bit...can't wait to sample the English dub. :P
I only have the HK Region 3 disc and I recommend that highly. It's got a great transfer and Dolby and DTS sound. Extras-wise, it got a few brief interviews (around 1-2 min each) with the two stars, cinematographer, and the director and the 40+ min making-of without any translation.
