Audio options are Cantonese Dolby Digital 5.1, Cantonese DTS 5.1 and Mandarin Dolby Digital 5.1 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 free from obvious spelling- and grammar errors. They go out of synch during one exchange towards the end but quickly get back on track. Traditional and simplified Chinese subtitles are also available.

A sparse selection of extras are included, starting with Ghost's File (1 minute, 17 seconds) a slideshow of images and Chinese text, with the majority of them being taken at various premieres for the movie. The Making Of (16 minutes, 56 seconds, in Mandarin and with permanent Chinese subtitles only) follows the usual routine format and the trailer (with optional English subtitles) for Rule #1 follows. The remaining two Chinese language options are promos for the film, with the first (1 minute, 1 second) containing English soundbites from director Tong, quick clips and interviews with supposedly real police talking of the presence of spirits while the second looks like a 30 second TV spot.
