David Kinsella thought he was going to North Korea to make a documentary. The North Koreans thought that David Kinsella would let them dictate the terms of his film. Both were wrong. After the government of Kim Jong-un brought in thousands of uninvited extras to help show the country as the regime wanted it seen, Kinsella knew he had to change his strategy and began framing his shots so that animation could be added in later. Mixing his Korean footage with scenes filmed in his native Belfast, the result was The Wall, the story of Yung Hee, a young female poet living under North Korea's regime that's told through a mix of live action and animation.
