The Dragon from Russia - Sam Hui (1990) - Yee Wo Street, Causeway Bay

Yao is first introduced to his assisstant, Teddy (also Yuen Tak) when he is attacked by the latter as some sort of skills test. Teddy breaks into Yao's apartment, which is supposedly located in the building at 60-62 Yee Wo Street (not sure if it has a name). They jump out of the apartment window and continue their fight along the top of the famous circular pedestrian bridge that straddles Yee Wo Street. This is the same walkway that was facsimiled and used for the finale of the live action version of Ghost in the Shell. They then run into Paliburg Plaza next door and this is supposedly where the 800 Dragon's have a base.
