North Korea's Secret Slaves: Dollar Heroes (TV Movie 2018)

North Korea’s Secret Slaves: Dollar Heroes: Directed by Carl Gierstorfer, Sebastian Weis.

“Interesting documentary with an important topic. But the use of hidden cameras when speaking to ordinary North Korean workers leaves a bad taste, even though they blur their faces and distort their voices. Was there any ethical concerns about how they were risking the safety of the workers who might be readily identified due to their build, clothes and location? I fully understand that it would be difficult to get them to speak on the record, but how do you weigh that against putting them in danger?”
