PROGRAM NOTE

Seo-young is family to a mother who is a long-term
 patient at a hospital and a younger brother, Young-jun,
 who has a disability. Working as an employee at a bigname
 supermarket, Seo-young cheats the customers
 by selling the products at a higher price or secretly
 stealing things she needs from the warehouse.
 However, she is soon found out and is fired from
 her job. The credit card bills are long overdue and
 her mother\'s medical fees are already more than
 what Seo-young can handle. Her brother works at a
 garment factory, but his salary is simply not enough to
 pay back their debt. Under these circumstances, the
 only person Seo-young can depend on is a monk who
 knows of Seo-young\'s unfortunate circumstances.
 Seo-young manages to get herself hired at a printing
 factory. But whenever the laborers in the workplace
 try to establish a labor union, the owner hampers the
 laborers\' efforts and discharges them. Nonetheless,
 Seo-young leaves her mother (her brother has
 committed suicide) and settles herself in a new place
 at the factory.
 Throughout the film, Seo-young several times
 mentions smelling a rotting odor. \'The blue mouth\'
 appearing in the title of this film is a metaphor that
 compares the mouth, the most unfamiliar part of the
 body, to a sewer with its wretched, rotten smell. A
 blue mouth is therefore a rotten hole. This putrid smell
 starts off in one person\'s body and quickly spreads
 to groups, religion, family, and everywhere else. In
 the last scene, Seo-young is diligently playing table
 tennis by herself. But the ping-pong ball falls into a
 hole and doesn\'t make a sound. Seo-young simply
 looks on, blankly. Is the blue mouthed face Seoyoung\'s
 own face or the face of the environment
 around her? [Sunah KIM]
