Back to Hong Kong again but staying with the tenuous link of Happy Valley and we have a quick snippet from the car scene at the beginning of the film as Frank follows his friend's car back to their house as he watches for anything untoward.
It's a brief glimpse but we see the cars driving down Wong Nai Chung Road on the west side of the Happy Valley Racecourse.
I must admit, I was a bit flummoxed by this place at first because the tram line made me spend a long time looking up and down the main tram route for a similar area - to no avail. It wasn't until I noticed that there is only one tram rail that I realised it must be a part of the line off the main route. My excuse is I haven't really explored this part of town other than visiting the nearby Muslim Cemetery
Anyway, the above Streetview grab shows the area today - hasn't changed a bit unsurprisingly other than the appearance of an extra high rise at the back. The wall on the right by the way marks the various cemeteries along this stretch of which the Muslim site is just one.
