China Rose - George C. Scott (1983) - Ruttonjee Sanatorium, Wanchai

Following up a lead, the two main characters head to the hospital where the son is supposed to have passed away. The location is actually the former version of the Ruttonjee Hospital. According to notes on Gwulo.com, the sanatorium stood until 1991 when it was then redeveloped (and renamed) into the hospital that still stands on the site today.

Judging by some of the surroundings the location of the old sanatorium was more towards the Queen's Road East side of the plot - where the current multi-function building stands

We also get a slightly closer view of the old entrance when the two later exit the building.
