Want there something about a previous NK leader kidnapping a South Korean actor and actress to satisfy his own whims about creating more movies with them in the lead roles?
I think what you're referring to was a South Korean actress and her ex-husband filmmaker being abducted back in the '70s. There's a book titled A Kim Jong-Il Production: The Extraordinary True Story of a Kidnapped Filmmaker, His Star Actress, and a Young Dictator's Rise to Power about this story, pretty fascinating.
