An early scene from Yang Li's "Blind Shaft", 2003.
Two partners will murder a fellow worker, pass it off as accidental and extort hush money from the owner of the mine.
Of the two, I find this shot more chilling for the man's casualness as he cracks his victim's skull.
Here the expression on the other conspirator's face reminds me of Goya. For example:
Take a few minutes and be humbled by Goya's Caprichos.
