According to users on the IMDB message boards (via Collider), where non-disclosure agreements go to die apparently, the studio has been test screening 'Witch Hunters' in two versions: one rated R and the other PG-13. According to pyromaniac975 who saw both cuts:
Good humor, good action, great fight scenes, awesome dynamic between Renner and Arterton. I loved it so much the first time, I made a group of friends go to the second screening the next week. But the next week, they had heavily edited it and turned it into a PG-13 film. If they keep it R, it’s gonna be great. Silly, but actiony and fun. If it’s PG13, it won’t be worth it. Let’s hope it’s an R rating.
It was graphic and gory, I had to look away a couple of times because it was just gross.
Meanwhile, RickCastle Writer compared the film tonally between "Scott Pilgrim Vs. The World" and "Drive Angry 3D." All this to say that IMDB commenters usually can't be trusted as far as you can (virtually) throw them. But it does perhaps indicate that director Tommy Wirkola, known for the Norwegian Nazis and zombies flick "Dead Snow," has left his mark on this for better or for worse. But R-rated or PG-13? Does it matter? This thing has turkey written all over it already.
Co-starring Famke Janssen and Peter Stormare, 'Witch Hunters' picks up with the fairly tale siblings fifteen years after the events at the gingerbread house. If that at all sounds remotely interesting to you, well, cross your fingers for an R-rating we suppose.
