With Saw IV less than two weeks away, rumors are already underway regarding the next installment in the decade's hottest horror franchise. Understandable, since fans have come to expect a new one every Halloween since 2004. Horror-Movies.ca is reporting that both Saw V and the recently announced Saw VI will both be directed by David Hackl, who served as production designer on the previous three films and was 2nd unit director for III and IV.According to producer Mark Berg on SAW the Blog, the team has been hashing out script ideas for next year's chapter while simultaneously prepping Saw IV for release later this month. Saw V goes before the cameras in January, and you can expect an October 2008 release--no shock there. How will the series continue with the villain already killed off? Since when has that ever stopped a successful horror franchise??
