The "Italian Hitchcock" is shooting the film in Italy, which will tell the story of a serial murderer with a taste for attractive women, who is being chased by a solitary detective. It stars Asia Argento, Ray Liotta, Elsa Pataky, Adrien Brody and Emmanuelle Seigner.
Dimension Films has acquired the film for US release later this year/early next year.
