The production was involved in a little bit of controversy when filming in Wanchai and poor old Neil was kidnapped by triads following an altercation between Dr Mark and a local thug and the rest you can read about in Martin Booth's rather excellent "Dragon Syndicates" book. Anyway, thankfully both are still alive and well and have moved on from the movie world.
The opening scene is very similar to the previously looked at Rush Hour 2 with a sweeping helicopter shot that starts at the back end of HK Island and pops over the mountain range to reveal the city below.
The various bits that are missing and under construction are a great reminder of my first trip to HK in late 95. The Cheung Kong Centre had yet to appear next to the Bank of China building (it was replacing the recently demolished famous Hilton Hotel) and you can see the new wing of the Convention Centre under construction in the harbour.
