According to a Philly blogger, they have the scoop on the exact location and even the name of a building where Jason is filming ‘Safe’.  However, they warn that you won’t get close by driving there, but may have a chance at a glimpse of Jason if go in by foot.  Earlier reports have mentioned that the public will be restricted to being across the street from the action, but with good telephoto lens, you could capture our hunk working on his new project.
