The Cantonese Dolby Digital 5.1 soundtrack is pretty terrific.The surrounds in particular creates an eerie feeling and the mentioned excellent sound design is apparent all over the sound stage. A Mandarin 5.1 dub is also included.

The English subtitles has some honest mistakes but did the job of conveying the plot well. Traditional and simplified Chinese subtitles are also included.

Mei Ah have included a few extras for once. The main one is two endings to the film. A few minutes before the climax, the movie stops and let you choose either the original ending or an alternate one called Day Of The Dead. Having to choose while watching was a highly annoying choice and Mei Ah should've put this option before the movie (the two endings are also selectable via the main menu). The alternate ending has optional subtitles, Cantonese and Mandarin soundtracks but is presented in fullscreen only.

Then there's an non English subtitled making of (21 minutes 23 seconds) called Story Of Big Head Monster. It starts with the trailer and next we get the usual mix of interviews and some decent behind the scenes footage.

After that, it's usual Mei Ah offerings starting with the Databank. This contains a plot synopsis and a cast & crew listing. The Best Buy option leads to a trailer for Matt Chow's United We Stand, And Swim.
