There is a saying in Korean: Over the mountains are mountains. Essentially, one hardship follows another. As proverbs go, it’s not exactly plucky. But when it comes to co-operating with a country like North Korea, it’s most definitely apt. This is why the movie Comrade Kim Goes Flying is so remarkable. Not only is it being released worldwide – nearly unheard of for a film shot in North Korea – but it is the very first feature film made within the borders of the infamous dictatorship with an entirely local cast in co-production with the west.
