Election - Simon Yam (2005) - Nam Sang Wai, Yuen Long

There are afew scenes that were shot in the Nam Sang Wai wetland area in Yuen Long. However, I think that in the film this is all supposed to be taking place over the border in the Mainland (or I may just have misunderstood what was happening).

The abandoned house where the gangsters are surrounded by the police is located there, as well as the scenes where Big Head (Lam Suet) gets beaten up by Gordon Lam. The rural road where Big Head is waiting for the truck to drive down is Nam Sang Wai Road on the eastern bank of the Shan Pui River. The camera shot through the windscreen of their car was taken almost directly opposite the (marked on Google maps as) "Northeast Electrical Enterprises Ltd" warehouse (which can be seen on left of screen in the third image).
