Moebius is a 2013 South Korean silent arthouse horror drama film written and directed by Kim Ki-duk. The narrative is conveyed entirely without use of spoken dialogue, written subtitles, or intertitles. Instead, characters communicate through vocables, and share moments of intensive gazing as a substitute for conversation. Moebius is also devoid of non-diegetic sound, with the exception of two scenes which mark the beginning of the film and the conclusion leading into the end credits. Moebius was screened out of competition at the 70th Venice International Film Festival. It was initially banned in South Korea, before the Korea Media Rating Board reviewed the film and changed the rating.

Plot

When the mother discovers that her husband is having an affair with a mistress, she attempts to enact her vengeance by castrating him. When her effort fails, she instead mutilates her son's genitals and cannibalizes his severed penis. The mother runs off into the night, abandoning the father and son. She passes a spiritual man on the sidewalk who is praying, and contemplates her actions.
