Visitor Q

Visitor Q is a 2001 Japanese erotic black comedy-horror film directed by Takashi Miike. It was filmed as the sixth and final part of the Love Cinema series consisting of six straight-to-video releases by independent filmmakers via a brief but exclusive run at the minuscule Shimokitazawa cinema in Tokyo. The six films were conceived as low budget exercises to explore the benefits afforded by the low-cost digital video medium such as the increased mobility of the camera and the low-lighting conditions available to the filmmakers.
