Soul 2 Seoul is a 25 minute documentary about a long time married IR couple (BM/AF) who are joined by their children to discuss their life as a bicultural/biracial family. Although they seem as if they have it together, things become tense when the oldest son marries a white female.
I found the sound hard to hear but it was worth muddling through.
Inja and James Yates have also started a foundation for biracial children. To find out more about it go to Soul2Seoul.org.
