The Silenced

During the argument between the Japanese officer and the Headmistress, the officer's haircut is very casual by Japanese military standards of that era. It looks more like a contemporary style. It's doubtful that a Japanese officer, or enlisted soldier, would have been allowed to wear his hair in such a way, as the style would more likely have been either closely cropped or very closely trimmed along the edges.

The fidelity of the props to the setting of Japanese Empire in Korea during the late 1930's is actually quite impressive. However, one detail kept cropping up over and over, and that is the intravenous (IV) equipment. What I see are spiked drip chambers using clear plastic and topped by white plastic spikes. Plus, the fluid runs through clear IV tubing regulated by white plastic roller-type flow regulators. These did not exist in the '30's. The standards of the time utilized rubber "surgical" tubing, metal thumb clamps, and rate controlled by eyeballing fluid volume administered over a given time, such as 4 ounces per hour. This would be read off of a scale printed or cast molded onto the side of the bottle.
