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.
