Directed by Jang Joon-hwan • 2003 • South Korea
Starring Shin Ha-kyun, Baek Yun-shik, Hwang Jung-min

Under the belief that Earth is being invaded by evil aliens who take the form of human beings, a seemingly unhinged amateur ufologist (Shin Ha-kyun) kidnaps a wealthy businessman (Baek Yun-shik) whom he believes to be a nefarious extraterrestrial—the beginning of a jaw-dropping, utterly unclassifiable sci-fi–horror–black-comedy thrill ride that spins off into increasingly insane, jaw-dropping realms. The visceral violence and genre-annihilating twists and turns gradually give way to something surprisingly humane and unexpectedly moving.
