Police Force - Wang Chung (1973) - Lam Tin Estate, Kwun Tong

Next up, Wong goes on a one man raid against a group of gangsters who are tooling up on a rooftop. This was filmed on top of one of the blocks of the old Lam Tin Estate. The first image shows Wong and side-kick (Fung Hak-on) standing on Kai Tin Road with Block 11 behind them. The small block was the fomer Pooi Shing Primary School. 

Judging by the angle on Kwun Tong Police station - which also features in the sequence when a bunch of cops are sent in as backup - then it looks like the rooftop fight was also filmed on top of Block 11. The whole estate underwent a staged demolition that was completed by 2002 and new blocks built to replace the old ones. In terms of the current area, Kai Yan House of the Kai Tin Estate, and the neighbouring carpark occupy the site where Block 11 used to stand.

The Killer - Chow Yun Fat (1989) - Hong Kong Society for Rehabilitation, Lam Tin

Arriving at the so-called "Scared Heart Hospital" - a very typical but hilarious Hong Kong spelling mistake, of course it should say "Sacred" - Ah Jong rushes the girl into the casualty department so she can be attended to.

In reality this was (and still is) a real medical facility. Originally constructed on Rehab Path as the Margaret Trench Medical Rehabilitation centre, by the time of filming it was the HQ of the Hong Kong Sports Association for the Physically Handicapped - later renamed to the Hong Kong Sports Association for the Physically Disabled. Anyway, it's still around and is now the Lam Tin HQ for the Hong Kong Society for Rehabilitation but now has several new buildings that form part of the Red Cross Princess Alexandra School. It looks like the boarding house of the school replaced the section containing the access slopes that Ah Jong can be seen running down once he makes his escape from the cops.
