The Cantonese/Mandarin Dolby Digital 5.1 track uses the jazz/stock porn score to a decent effect in the front speakers but there's otherwise low activity in the track. A Mandarin 2.0 dub is also included.

The optional English subtitles are free of obvious grammar- and structure errors.

Extras includes a Tai Seng promo for Cop On A Mission and an alternate opening sequence (6 minutes). Featuring imbedded Chinese/English subtitles and Cantonese 2.0 audio, extended opening sequence is the more appropriate description as this segment adds about 3 minutes of footage with the couple Daniel Wu's character first is hired to spy on. It starts the movie shaky but reveals Category III-esque sleazy intentions. Comes with the price of the actual slightly atmospheric opening now feeling less so.
