These days it's the location of an MTR station which gets tourists to nearby Disneyland, but in 1983 it was the location used for a scene when Sammo Hung leads the gangsters to his cache of hidden guns only to find that JC has beaten him to it - leading to a bit of a set to with the odd evil henchman.
The landscape has changed significantly thanks to the MTR station and Lantau Link road which takes drivers to the airport (oh yes and the Airport express train that also thunders by) but the background ridge lines remain, as do the odd wooden poles sticking up out of the water.
