The Fighting Dragon - Yasuaki Kurata (1975) - Excelsior Hotel, Causeway Bay

The film tries to trick us into believing that the Excelsior Hotel is in Macau, because this is Lung's next stop as he tracks down the man responsible for hiring the thugs to kidnap the woman at the airport. It looks like the interior scene may have also been shot in the hotel with the obvious view over to Kowloon and Beacon Hill in the distance. Then, the next scene we are back in Macau again.
