Lou Lumenick of the New York Post says Saw IV, which opens this weekend, “is not being screened in advance, natch”. No surprise there, since Saw III wasn’t screened for critics either. I can’t recall if Saw II was. I do know that the original Saw is the only film in this series that I have seen, and that is because there was a press screening for that one, way, way back in 2004.
