The Cantonese 5.1 Dolby Digital track does lack that power you expect from a movie like this but generally does the job. Music spreads out nicely and the effects envelop the viewer to a decent degree. A Mandarin 5.1 track is also included.

No problems in the English subtitles besides a few spelling errors and the fact that dialogue sometimes is very fast, resulting in the subs appearing very briefly at times. Traditional and simplified Chinese subtitles are also included.

Universe has loaded up with more extras than usual starting with the 15 minute Making Of (no subtitles). Shot entirely on film and letterboxed, we're treated to enough behind the scenes footage for the viewing to be rewarding.

Next up are short Star's Interviews (English subtitles) with director Johnnie To, actors Ruby Wong and Raymond Wong. Following the usual Universe dvd interview pattern, the viewer click a question and is then taken to a 30-60 answer clip. To manages to hand out decent info in the brief time, most interesting the talk about the challenges of making fire sequences (not done this extensively before in a Hong Kong movies). The actors add small notes about their research and the grueling, long shoot. Welcome extra but you wish Universe would produce longer segments like this.

Star's Files for Lau Ching Wan, Alex Fong, Carman Lee, Ruby Wong and Johnnie To are next and only briefly go over the careers the people choosen. The theatrical trailer for Lifeline appears plus trailers for Expect The Unexpected, The Longest Nite and A Hero Never Dies.
