In 1962, James Dresnok defected to North Korea. Very little was known about him after that. In 2006 they made a documentary about him called Crossing the Line. The link above is part 1 of the documentary on youtube. They've split it up into six 15-minute segments on youtube,
I'm particularly interested in whether or not he is honest when he says he's happy in North Korea and when he claims Charles Jenkins (another deserter who married a Japanese woman in North Korea and returned to Japan with her in 2004 -- he served a 30 day sentence for desertion) is lying about his life in North Korea.
