I believe the best option is to make a "frame movie."

They should make a movie about the process where
a group of pro-North Korean directors and actors conspire to distort the Moon Se-kwang incident,
the process of replicating North Korean films,
and the process of brushing it all off with excuses.
They can include the "affinity" with the Democratic Party as a "conspiracy theory."
I'm talking about cinematic imagination.
