|Let the Bullets Fly (Rang zidan fei) (Blu-ray)||R3|
The Region A US Blu-ray has the same technical specifications but adds a “making of”, interviews and trailers. The Region A Hong Kong release has a DTS-HD MA 7.1 audio and extras including interviews, the “making of”, cast profiles, promos and poster gallery. It has English subtitles for the feature but they may not be available for the extras. The Region All Chinese release seems similar to our Region B.
Probably the Hong Kong version is the pick.
