Another Saw director moves on as David Hackl (Saw V) is attached to direct Jack Reher’s spec script The Red Machine, reports TheWrap. The story follows two estranged brothers who go on a camping trip and are continuously attacked by an erratic bear that has lost its fear of humans. Hackl served as the production designer on the second, third and fourth Saw movies. He also worked as the second unit director on Saw III, Saw IV and Repo! The Genetic Opera. Hackl was set to direct the seventh installment in the successful franchise, Saw 3D, but was forced off the project only two weeks before principal photography began by Twisted Pictures at Lionsgate’s request, so that the studio could exercise a second picture option on Saw VI director Kevin Greutert in order to prevent him from directing Paranormal Activity 2, which is a rival horror franchise. Hackl is also attached to direct an adaptation of Vince Churchill’s novel The Butcher Bride, which is currently in development and was also written by Reher.
