Na Hong-Jin is coming to Busan's Master Class lineup this year with a film — "Hope" — that most Western audiences will never see. But it is his earlier work, particularly "Memories of Murder," that matters for anyone learning screenwriting right now. It reveals something the festival announcement misses entirely: the actual teaching will be about dismantling genre, not perfecting it.
In "Memories of Murder," Na constructs what should be a serial killer thriller. The machinery is there, the stakes are there, the moral weight is there. Then he does something most American films will not do. He makes the investigation itself the subject. Not the killer. Not the solution. The suffocating inadequacy of the police procedural when confronted with a crime that doesn't fit the tools designed to solve it.
This is not innovation in plot. It is a decision about what story actually matters. American screenwriting software. The architecture taught in MFAs and distilled into save-the-cat story beats. Treats genre as the skeleton and character as the meat that moves it. You choose a genre box. You fill it with character decisions. Na's method reverses the hierarchy. He begins with the specific texture of how institutions fail. Genre conventions become a problem to solve rather than a form to master. "Memories of Murder" could have ended with an arrest. Instead, it ends with the absence of one, and the film's refusal to close that door is the entire point.
When Busan invites him to teach, students will arrive expecting masterclass lessons in thriller construction. What they will encounter instead is an argument about fidelity to what a story actually investigates rather than what its genre promises to deliver. For directors trained to see plot structure as neutral and universal, this is not a technique. It is a confrontation with how differently filmmaking can be organized.
It matters because American audiences are hungry for the thing that Na's work does. Moral ambiguity, institutional critique, the possibility that some problems don't resolve. But the screenwriting education that feeds the industry still teaches toward closure and genre satisfaction. Na's presence at Busan is not a celebration of another directorial voice. It is the arrival of someone teaching the opposite of what most narrative training programs assume is true.
Stream "Memories of Murder" and notice which scenes have no dialogue—Na uses silence and procedural detail where American films would cut to exposition.
