虐杀电影（2012）

A group of ambitious filmmakers set out to create the world's first reality horror movie. Their plan was simple; they'd offer an active serial killer complete anonymity and a worldwide platform from which to display his work in exchange for genuine footage of his grisly crimes. What ensues is a hellish game of cat and mouse as a cryptic filmmaker, known only as The Maestro, comes out from hiding in search of his "perfect shot".
