The fight in the comments section to the OUT OF DARKNESS trailer is particularly interesting because apparently there’s been research in when humans actually started shaving themselves, and cutting their hair. I’m not an expert on the subject myself, by any means, but when you think about it logically: wild, unkempt hair gets stuck, in the way, and everywhere. It actually kind of makes sense that hunter cultures would start grooming themselves as soon as possible.
Oh, and this is either a supernatural monster movie, or a sabertooth movie. Which I guess would make this a natural monster movie, then.
