One of the key scenes in this film is when the police conduct a raid on the Shek O hideout of one of the main bad guys. Despite being in HK for over 10 years I still haven't made the effort to visit Shek O so I can't tell you exactly where these scenes were but perhaps someone reading can tell us which house it was. Although if yopu look at the top picture you can see the Tin Hau Temple roof in the background. Movie cameras being as they are though, it's hard to know how far away the roof top is that the guy (the actor is Richie Coster) is sitting on. Of course, the well-known landmark of the local Tin Hau Temple has featured on this blog previously.
