Long story short: the most famous actor and director in South Korea (who happened to be a divorced couple) were kidnapped by Kim Jong Il in the late 1970s, held captive and forced to make, edit, and review movies for North Korea until the mid-80s when they escaped in Vienna after a car chase through the streets that ended in heavy traffic where they jumped out and ran on foot to the US embassy.
How has this never been made into a movie?
