Italian horror maestro Dario Argento is back with a new film, Giallo. Real horror fans know this guy doesn't play games. Oddly enough, Giallo is actually a genre of Italian movies Argento helped popularize based on a series of yellow-covered novels. Makes sense then that the serial killer in this flick is named Yellow. He's slaughtering models and all that, but you just want to watch the trailer, right? Hit the jump for the goods.
