Queen Elizabeth II made a famous stop off at the Oi Man Estate in Ho Man Tin when she made her royal visit in 1975 and the actual footage of that trip was incorporated fairly seamlessly into the film whereby the imposter Queen (a double brought in to hide the fact that the real one has been kidnapped by Mickey Rooney) enters one of the flats and it's occupied by some scruffy dude wearing only underwear.
I'm not sure which block the Queen is walking along in the third picture, but judging from the current maps she was walking along a section of Kar Man House. Clarifications welcome.
The Oi Man Estate was newly opened at the time of the Queen's trip and was being showcased as the model for Govt housing in HK. It looks like the French film crew returned to the same spot for their own shoot and, actually, even today it looks pretty much the same other than sporting a different paint job.
