North Korea's prison system and the cult of personality surrounding the Stalinist nation's leader Kim Jong-Il are the subject of a documentary screening at the Sundance Film Festival.
Director NC Heikin's film "Kimjongilia" aims to lift the veil on the most isolated country on earth and offers a vignette of North Korean leaders Kim Il-Sung and his son Kim Jong-Il.
Heikin interviewed more than a dozen survivors of North Korean jails for the feature, which is also interspersed with archival footage of propaganda films and original scenes that illustrate daily life.
"It's a big, untold story on human rights. I want to get the word out that people are suffering," Heikin told AFP.
