Crossing the Line movie (American defector in North Korea)

I just watched this documentary last night.  It's a fascinating look into the mind of an American GI who defected to North Korea in the 1960s.  I am surprised at how much leeway the North Korean government allowed in interviewing and following this guy throughout Pyongyang.  It is more about the man and what makes him tick than politics and ideology.  James Dresnok had a rough childhood in Virginia.  He was in foster homes and dropped out of high school.  He deserted when his marriage failed.  He was lauded as a hero in North Korea but tried to defect again by approaching the Soviet embassy (he failed).  He has a blond haired adult son with a kidnapped Romanian woman (who passed away).  He is now married and has a young son with the illegitimate daughter of a Korean woman and Togolese diplomat.  The story is strange and I've barely touched on the truly bizarre parts.
