What a movie this would make! in 1962, an american deserted/was kidnapped into/by North Korea. While there he starred in a propaganda film as a sinister, cigar-chomping american.
He was there for many years, all alone with his north korean captors who could barely speak English. Then, in the 70s, NK started kidnapping Japanese to use as translators. They'd grab them at night and then bring them back in little two man submarines. Nobody in japan even knew what happened, they suspected kidnap but NK always denied it.
Somehow the american met one of the kidnapped japanese women, and love blossomed. They got married years ago, and now have children.
Eventually the woman was released from NK and went back to japan. Her sick husband stayed in NK because he was afraid the US would try to prosecute him. Now he's just gone to japan, and is in hospital. The US has announced that they won't try to extradite him (until he gets better...?)
Things you could put in the movie:
1. stupid american military, allowing a dude to just jump across the dmz line into NK
2. stupid NK captors, language errors, laugh at their fanatacism
3. loneliness and linguistic isolation, brightened by when he first heard that NK would start kidnapping japanese. maybe he'd have some company...
4. he first meets her ... it's tough to communicate but they both feel love, and spend all their time together.
5. there were only like 10 or 20 foreigners in all of NK. Their love triangles and friendships.
6. the joy of her returning to her homeland.
7. cowardly american military threatening a guy 40 years later, preventing him from going to japan to see his wife.
