Escape

both focus on soldiers defecting
both star Koo Kyo-Hwan
i think Koo Kyo-Hwan’s characters in both are kind of similar in the sense that they both have a dark sense of humour .

Both movies are set at the DMZ and are a military thriller. Both have elements of tragedy and brotherhood. The difference is in the story. Escape is focused on a North Korean soldier who wants to desert to the South, whereas Joint Security Area is focused on the events that happen between a group of North and South Korean soldiers.
