This rocky outcrop is at Fei Ngo Shan or the Kowloon Peak; not somewhere that you'd want Tony Leung to put you in a box and kick you off...
Thanks to the eagle-eyes of Phil from the Hong Kong (& Macau) Stuff / Hong Kong (& Macau) Film Stuff blogs, who is quite the spotter. Oh, and as there's no image on Street View, I've used one from TripnTale.com (thanks nowzone), which shows the same outcrop.
