Whispering Corridors is a 1998 South Korean supernatural horror film directed and co-written by Park Ki-hyung. It was part of the explosion in South Korean cinema following the liberalization of censorship in the aftermath of the end of the country's military dictatorship. The film makes a social commentary on authoritarianism and conformity in the harsh South Korean education system.

Memento Mori is a 1999 South Korean horror film, and the second installment of the Whispering Corridors film series. It is a sequel to 1998's Whispering Corridors, and is also set in an all-girls high school, but the films are otherwise unrelated. Memento Mori was one of the first Korean commercial films to depict lesbian characters. However, prevailing Korean attitudes constrained its potential to be widely viewed, even more so as the controversial themes targeted the teen demographic.
