Strangers - John Simm (2018) - H.K.W.W Yuen Long R.G Filters Building, Yuen Long

The venue where Lau is taken by her kidnappers is an old Hong Kong Water Works facility on the Tuen Mun/Yuen Long district border. For some reason the "Yuen Long R.G. Filter" is no longer on the Film Services website despite their photos of it popping up when you do a Google search. Perhaps they have decided to rebuild it and so it is no longer available? Anyway, it looks like the interior was also filmed on location.
