The Killer - Chow Yun Fat (1989) - High Street, Sai Ying Pun

The (former) location of Ah Jong's apartment is revealed in a couple of shots that feature, at least bits of, Kau Yan Church in Sai Ying Pun. On the south side of High Street, directly opposite the church, was a row of four old tenements occupying #80 thru #86 High Street. One of these (I don't know which) contained Ah Jong's apartment. Sadly - and this seems to be a common theme in John Woo films, so perhaps explains why he tends to destroy them with exploding squibs - all four of the buildings were demolished just shortly afterwards and Lai Yin Court was constructed in the same space.

In the first images below we are looking from behind the stone steps in front of the church up at where we assume Ah Jong's apartment is. I've included a couple of interior views which I have no doubt were filmed on site. And finally the view from Ah Jong's window shows the front of the church roof.

The Killer - Chow Yun Fat (1989) - Hennessy Road, Causeway Bay

Back to Causeway Bay and this time we're the oposite end of Yee Wo Street as Detective Lee chases the bad guy onto a tram.

The Killer - Chow Yun Fat (1989) - Lung King Street, Wanchai

This is the small side road where the police try to pull off their firearms sale sting before an unwitting traffic cop shows upon his bike and ruins it all, causing a shootout.

The establishing shot for the police sting sequence is looking west along Yee Wo Street with SOGO in the distance and the junction with Paterson Street on the lower right. This shot was most likely captured from the circular walkway that connects Pennington Street with Sugar Street.

The Killer - Chow Yun Fat (1989) - D'Aguilar Street, Central

After rescuing Jennie from some attackers, Ah Jong walks with her up D'Aguilar Street. These days this street has lost much, in fact all, of its previous character following the removal of the large stone retaining wall on the right (replaced with high rise buildings) and the stone cobbles (replaced by asphalt).

The Killer - Chow Yun Fat (1989) - Lan Kwai Fong, Central

As Jennie (Sally Yip) makes her way home from the club, she can be seen walking up Lan Kwai Fong. Genre fans may recall that City on Fire used a similar shot, taken in almost the same place, a few years prior. The wall at the back is on D'Aguilar Street but was demolished quite sometime ago.LKF Tower currently sits there.

The Killer - Chow Yun Fat (1989) - View from the Peak

Next up The Killer, the John Woo classic. To kick off my deep dive into the locations we start with the opening scenes taken from the Peak and looking down into the harbour. It's a night shot so it's difficult to make out much detail other than the fact that the Bank of China Tower still looks to be under construction. You can compare its condition to this recent post for Police Story 2 which was filmed not that long before (6 months?).

If you are here to finally find out where the famous church from the finale was located, I'm afraid you will be disappointed because I don't believe it was a real place. However, some other locations for several of the set pieces were real and I have managed to track a few of them down.

Peninsula - Gang Dong-won (2020) - Canton Road, Mongkok

The gang take Jung-seok to see their boss (Geoffrey Giuliano) and the establishing shot for this part is of Canton Road. The big red sign in the top image, as well as the "Harbour Hotel" (aka the Harbour Inn as it is now known on the interwebs) sign, are still around. This is the stretch of Canton Road between Shantung Street and Soy Street.
 

Peninsula - Gang Dong-won (2020) - Sai Yeung Choi Street South, Mongkok

I can't quite remember what the context of the next shot is but I'll leave it here anyway. I think it was just one of those incidental shots that joins two scenes together - in this case the change from the bosses apartment to the noodle shop where Jung-seok and his brother-in-law have a bit of a heart to heart. Anyway, it's Sai Yeung Choi Street South just north of Mongkok Road.

Peninsula - Gang Dong-won (2020) - Reclamation Street, Mongkok

This is the street location used to show where Jung-seok lives. It's shown as several gang members make their way to his apartment to take him to see their boss.

This is the section of Reclamation Street just north of Argyle Street in Mongkok. The shot starts looking up at some of the buildings on the west side of the street (we're looking south in this brief sequence) before panning down to street level. As a great example of how things often look very different on film, I often catch the bus home from the bus stop at the bottom of those buildings and am here quite often. However, I still had to search for where the "H1 Hotel" is (you can see it in the background) in order to find the location.
