The reason why the main character tries to back out of the "film" he's making is because the director shows him a video of a newborn baby being raped (and for the record, it doesn't die, it's still obviously a very nasty scene though), so presumably in the cut version there is no real reason for him to back out of the movie? Likewise, the end of the film see's the protagonist inadvertently raping his young son, which consequently senRAB him over the edge leading up to the grim ending, which with these scenes removed will make absolutely no sense...
