Premise: The Last Witness () is a 1980 South Korean mystery film directed by Lee Doo-yong, based on the 1974 novel of the same title by Kim Seong-jong. When the film was originally released, a 40-minute portion was cut due to censorship laws of that time. A remake with the same title was released in 2001.
Hypothesis: Censorship of the film saw the film cut 5/6 of an hour run time out.
