6 Underground - Ryan Reynolds (2019) - Stonecutter's Bridge, Kowloon

Next up is another film from Michael Bay. You may recall that Bay was in Hong Kong circa 2014 to film scenes for Transformers: Age of Extinction. The filming caused a fair bit of controversy thanks to his merging a national park in China with the Hong Kong Island geography (which led to complaints from the Chinese park authorities) and also due to the extortion incidents that occurred in two major filming locations (Quarry Bay and Sham Shui Po).

The events here seem to have put Bay off from returning (and who could blame him?) because the Hong Kong scenes used in this film are a combination of brief establishing shots and the main set (which was actually in Italy) having a variety of locations, including Hong Kong, inserted into the background.

It looks as though Bay has basically reused footage he shot for Transformers and included some small shots that maybe were not originally included in that film but kept in store for such a purpose. My theory appears to be correct when you compare these opening HK shots for 6 Underground with a similar scene in Transformers: Age of Extinction. The opening shot is a view along the Stonecutter's Bridge that links Kowloon and Stonecutter Island with Tsing Yi Island.
