Like millions of movie-mad children around the world, Gim Gyu Min dreamed of being a film star when he grew up. But when he huddled in the darkness of the cinema in the 1980s and ’90s, he was forced to watch propaganda praising the North Korean regime.

Now, after a harrowing escape from his country in 1999, he is a filmmaker dedicated to making movies that expose the human-rights abuses there. “I want to let the world know that more and more people are dying under the Kim family dictatorship,” he said.

His movies are based on events that he witnessed during the North Korean famine in the late 1990s, when, among other horrors, he watched a woman being arrested for cannibalism after she resorted to eating her own son. Her child’s head had been found in a cauldron.
