The imporovising?! (Possible SPOILERS)

So, according to the trivia A LOT ( if not most) of this was improvised. It's a special kind of creepy where a person could come up with a story about raping their wife who likes watching beastility pornography!!! I mean, I enjoy creepy and messed up but to just "improvise" that and use it in a movie is the ultimate creepy/messed up!! I did like the movie tho. Mark was creepy!!
