Righting Wrongs - Yuen Biao (1986) - Mita Centre, Kwai Chung

Although in the film Biao follows his target into the Great Eagle Centre, the shot of him abseiling down the side of the building - both before and after the killing - was filmed elsewhere. This is where GoogleEarth's 3D rendering of Hong Kong has become invaluable because it "only" took me about 30 minutes of searching to identify the correct building as the Mita Centre in Kwai Chung. Luckily it's still standing otherwise the search may have taken a lot longer. This film shows the building from the north side so here is a Streetview link.
