She Shoots Straight - Joyce Godenzi (1990) - Sai Wan Military Cemetery

Bo (Tony Leung) is laid to rest at the Sai Wan War Cemetery. In reality, when a civil servant dies in the line of duty, they get to be buried at Gallant Garden in Wo Hop Shek. Mina spots the Viet gang boss just prior to him blowing up a bomb on the grave.

Hacker - Callan McAuliffe (2016) - Cornell Centre, Chai Wan

The group rent a space in an industrial building from where they can run their credit fraud schemes. It looks like the film company rented space in the same building where Crossing Hennessy did a few years before, although it looks like in this film they used a lower floor.

Crossing Hennessy - Jacky Cheung (2010) - Cornell Centre, Chai Wan

Man-Yu's new studio space is located in the Cornell Centre, an industrial building in Chai Wan. It looks like we have a rare incidence where the exteriors and interiors were filmed at the same place because the view from the studio is one that matches the view that should be visible from the upper floors of the Cornell Centre.

Infernal Affairs - Andy Lau (2002) - Chai Wan North No.2 Fresh Water Service Reservoir, Chai Wan

The final grave scenes in the movie almost look as though they were shot on the roof of a building with some astroturf laid down, but it turns out that the grass is real and belongs to the Chai Wan North No.2 Fresh Water Service Reservoir which sits on the north slope of Sai Wan hill (the same hill that has the battery at the top and the not-so-long ago mentioned Lei Yue Mun Holiday Park). It's possibly a popular filming spot because it has its own entry on the film services office website.
