Le Monocle Rit Jaune - Paul Meurisse (1964) - Carnarvon Road, Tsim Sha Tsui

There is a brief meeting between the main character and his love interest as he leaves a Japanese sauna. The next shot is supposedly outside the sauna as we look down Humphrey's Avenue in Tsim Sha Tsui. It's possible the building on the right is Humphrey's Court but I don't have anything to compare it to.

Never mind as the next building is unmistakable, it's Carnarvon Mansion which stil sits (and looks almost exactly the same) at the junction where Humphrey's Avenue meets Carnarvon Road (amongst others).

The building at the end of the road (on the left) is Mirador Mansions.

Bons Baisers de Hong Kong - Les Charlots (1975) - Nathan Road, Tsim Sha Tsui

There's some nice colourful street scenes in this film including this brief look north up Nathan Road near the southern end. You can see the Holiday Inn sign which puts us in familiar tourist territory. Both Mirador Mansion and Chungking Mansions can be seen either side of the Holiday Inn - Chungking Mansions being closer to the camera..

Note the Royal paraphernalia draped on the lamp posts. Don't forget this film was made the same time as the Queen's 1975 trip to HK and utilises a lot of the footage from that for its own plot.
