Hard Boiled - Chow Yun Fat (1992) - World Trade Centre, Causeway Bay

The Police Chief (Philip Chan) goes to meet his undercover operative (Tony Leung) on a rooftop overlooking Causeway Bay Typhoon Shelter. The roof top is the World Trade Centre, we know this becaue as Tony leaves the meeting, the camera follows him to the right and you can just see the curved front of the (recently demolished) Excelsior Hotel at the side of the screen (see last image).

Foxbat - Henry Silva (1977) - Gloucester Road, Causeway Bay

Silva's contact for the espionage deal is a fashion designer and they first make contact at one of his shows being held at what we are led to believe is the World Trade Centre (built 1975) in Causeway Bay. Here is the establishing shot that shows us the front as well as the Excelsior Hotel next door. Sadly, the Excelsior has closed and is currently (April 2020) still being demolished.
