I’m not really into these films, but for those that are, here is the latest trailer for SAW IV. Scheduled for a 10/26/07 release, the latest installment is helmed by young director Darren Lynn Bousman who also directed Saw II and Saw III. All together, the first three Saw films only cost $15 million to produce. Worldwide, the Saw franchise has pulled in over $400 million in box office receipts. With returns like that for distributor Lions Gate, who knows when we’ll see the last Saw film.
