All About Ah Long - Chow Yun Fat (1989) - Bonham Road, Sai Ying Pun

During the opening credits as Ah Long takes Porky to school there is a shot of the pair as they ride along Bonham Road. In the background you can see the main entrance of King's College at the top of Western Street.

Chinese Box - Jeremy Irons (1997) - King's College, Western Street

The official address of King's College is actually Bonham Road, however our view courtesy of the film is of the large double door entrance at the end of the complex along Western Street. The arched doorway at the back is one of several that overlook the inner sports ground.

Here's a Streetview grab of the same door, it looks like it has had a new frame fitted but other than that not much has changed.

The school is one of HK's oldest and most prestigious and has several noted alumni including Stanley Kwan - the creator of HK's famous Hang Seng Index - and the tosspot who masquerades as Hong Kong's current Chief Executive, Leung Chung D7689 (or something like that...).
