|Vengeance (Fuk sau)||R4|
There apparently is a Region 1 US release but I cannot find any details. The Region 3 Hong Kong release has Chinese language options, the English dub and only the trailer as an extra. Our Region 4 is fine.
The Region A Hong Kong Blu-ray has the trailer and more language options, the Region B UK Blu-ray has a “making of” (10:10) and different language options.
