Welcome to North Korea [pt 2/6]
This film, shot mostly covertly, shows the irony of a regime where 20 million people lived in poverty, some on the brink of starvation, while former dictator Kim II Sung built extravagant monuments to reflect his power.

Monuments and museums pay homage to them, but they are strangely empty.
