The Killer - Chow Yun Fat (1989) - Kwun Tong Public Pier, Kwun Tong

Where Ah Jong goes to contemplate his life after realising he had been double-crossed. The Kwun Tong Public Pier is the smallest of the 3 piers at this location, the other ones being the ferry pier and the vehicular ferry pier. Judging by the amount of mist on the harbour, I would say this scene was probably filmed around this time of year (March/April) as the air starts to warm up and the humidity starts to creep up. The harbour does sometimes get this weird thick covering of fog so it was good timing to capture it on film.

Push - Chris Evans (2009) - Kwun Tong Public Pier, Kwun Tong

There are three piers along the Kwun Tong harbourfront. One is the ferry pier where the supermarket crash scene in Knock Off was filmed. Another is the vehicular ferry pier still used for transporting dangerous items across the harbour (the drivers are banned fro using the tunnels for obvious reasons) and finally there is the public pier which is basically free for anyone with a boat to stop and pick up/drop off.

This scene in Push was filmed around the latter, smaller pier. It's when Nick and Cassie (Evans and Dakota Fanning, respectively) stumble across a recently memory wiped Kira. In the background of the lower picture you can see the entrance ramp for the vehicular pier.

Look at the Streetview picture below and you can see that the graffiti on the pier column was still visible when the Google car drove by.
