The Dolby Digital 5.1 cantonese sync sound track sounds wonderful also. This is a movie that is dialogue heave but perfectly uses the other speakers for music and ambience. I noticed some slight distortion in the dialogue at times but that's being picky. A mandarin 5.1 track is also included.

The english subtitles are very good with minimal spelling errors and such. Shame though that they're placed partly on the widescreen frame. That's really annoying for us widescreen tv owners! Traditional and simplified chinese subtitles are also included.

Extras consists of two quite good trailers for this movie and the theatrical trailers for Purple Storm and Gen-X Cops (with the anti piracy message at the end).

There's also fairly good biographies for actors Etic Tsang, Nicholas Tse, Kelly Chen, Shu Qi, Stephen Fung and Sam Lee. I was kind of disappointed that director Riley Yip didn't get a biography though.

As a final note I just wanted to say that Universe should put the language and subtitle menus on the main menu, not the special features one.
