Operation Chromite (2016)

A mostly Korean but occasionally English language war movie 'inspired by' true events; i.e. the Korean War, a conflict in which the communist North, with the support of China and Russia, invaded the South, who were aided by the US.
The film follows a squad of soldiers from the South who undertake a covert operation in the North. The Korean actors are well-suited to their roles, whether that be as daring, selfless hero types or as stand-offish and overwhelmingly suspicious murderous types, but the Western actors are less successful, In fact, while I generally like Liam Neeson he's a piss-poor choice to play US military leader General MacArthur. It boggles the mind why an actor with a discernible N. Irish accent was considered good for the role.
