• Audio commentary with director Dante Lam, writer Jack Ng and production designer Yau Wai-Ming. Covering casting, subtext, finding a true Hong Kong feel via locations, creating the car chase, research, nuances of what respect means in Chinese society and Zhang Jing-Chu working on her Cantonese, the track is certainly informative. Nothing truly groundbreaking information-wise but the anecdotes of how much the twin kids playing Ling got pushed and worked would horrify Hollywood producers. The trio also leave a fair number of gaps and simply describes the ongoing story at points.
• Preview-section contains the trailer and 4 TV spots.
• The Making Of (13 minutes, 56 seconds) follows the formula but gives us a better insight than usual. Especially the stories and behind the scenes footage from key sequences such as the car crash and when little Wong Suet-Yin gets buried in the sand. Nicholas Tse's devotion to the acting and Dante Lam the technical perfectionist also gets covered.
• Behind The Scene (23 minutes, 23 seconds) extends a whole lot on the footage shot by the making of crew, with focus on scenes such as the car chase and Wong Yuet-Sin getting the sand dumped on her.
• Deleted Scenes (21 minutes, 10 seconds) contains approximately 9 clips, most of which are extensions of no interest. Of note is a longer scene showing Hung's first kidnapping victim peeing herself as she's dying from the poison, the police almost catching wind of something being wrong in Hung's apartment after his old lady neighbour has called them about the plumbing and an ending coda that wraps matters up by talking but is clearly one too many scenes for an audience about ready to go home.
