James Wan and Leigh Whannell took the horror world by storm nine years ago with Saw, and they continue their legacy of thrills with this month's Insidious Chapter 2. FilmDistrict has released a featurette with the director and co-writer/actor, where they explain how they were able to up the ante with even more scares than the 2011 original Insidious. Stars Patrick Wilson and Rose Byrne also praise the filmmakers for their knowledge of the genre, and we also see new footage from this sequel, in theaters September 13.
