Even with the invention and proliferation of television, radio remains a relevant and fascinating medium. There are some excellent films about the power of the DJ voice, from Talk Radio to Pump Up the Volume to The Fisher King. Something about the disembodied voice allows the listener to imagine any person they choose as the owner of that voice, and twist the words to their own ideals. Sang Man Kim’s new thriller Midnight F.M. can easily be added not only to the radio film canon, but also to the slate of great thrillers being produced in recent years in South Korea.
