to all you hoping for more gore in NC17
I'm sorry to break it to you, but I wouldn't get my hopes up too high for a much more violent version.
The MPAA doesn't really have a problem with graphic violence in films since the early 2000's unless it's insanely over the top. If you saw the movie This Film Is Not yet rated you'd know they have a much bigger problem with sex in films as opposed to violence. All of the violence presented in this film has been done a million times already so in regards to the violence, don't be surprised if the NC-17 version only features a few extra frames of gore.
I also read many months ago that RZ's main problem with the ratings board consisted of (no surprise) the sexual content in this film. So expect so see more graphic sexuality as opposed to graphic violence.
I could be wrong but I highly doubt it. Also I just want to say, RZ cutting this movie in the first place so it can play as rated R in one fathom event screening is beyond absurd.
It could've went straight to dvd/vod/bluray in it's unrated cut and he wouldn't have lost a dime.
