Audio options are Cantonese Dolby Digital 6.1 EX, Cantonese DTS 6.1 ES and Mandarin Dolby Digital 2.0 but as I'm not equipped with such a system, my assessment of this disc aspect will be left off this review.

The English subtitles are generally very coherent but clearly stumbles a bit at times in the grammar department. Nothing a sensible mind wouldn't be able to work through though. Traditional and simplified Chinese subtitles are also included.

The trailer and an English subtitled Making Of (10 minutes, 45 seconds) make up the extra content. The Making Of has the actors discussing characters, approach to acting and development while director Lee talks of working with actor's real personalities when creating characters. Minor info but still info.
