The Brain Stealers - Lily Ho Li-li (1968) - Diamond Hill Cemetery, Kowloon

Pretending that their father has been killed, the siblings go through a mock funeral for him to throw the kidnappers off his scent. This scene was filmed at the Diamond Hill Cemetery.

Just Heroes - David Chiang (1989) - Diamond Hill Columbarium

I've only recently worked out where the funeral for the murdered gang boss takes place. It's been completely changed since this movie was made (you can see how it looks today here) but this is the Diamond Hill Columbarium on Po Kong Village Road. About the only things that remain today are the triangular roofed niche pavilions that can be seen in the background and the looped service road that can be seen in the top two images.

Karate from Shaolin Temple - Kazuma Kenji (1976) - Diamond Hill Cemetery, Kowloon

The cemetery at Diamond Hill features in several scenes of this movie although this was before it underwent a massive modernisation and many of the graves on the lower slopes (near to what is now Po Kong Village Road) were removed/relocated for the construction of new columbarium and crematorium buildings (that can be seen here). This movie was also shot prior to the hill - the "Diamond Hill" that gives the area its name - being removed to make way for what is now a cluster of schools and the Po Kong Village Road Park. Hong Kong is big on preserving names, but physical things...not so much.

Strangers - John Simm (2018) - Diamond Hill Columbarium, Po Kong Village Road

Jonah finally meets up with the investigative journalist who is probing around his wife's death. They meet, quite aptly, at the Diamond Hill Columbarium (an urn cemetery where cremated remains are kept in wall niches). This particular one is fairly new (built in 2008) but lo-and-behold it is one of the places offered via what was the Hong Kong Film Services Office, but has since been renamed the Film Promotion and Facilition Section of the Cultural and Creative Industries Development Agency. Yes,that is definitely much catchier and easier to say than "FSO". Here's the updated link.
