[[WMG: Sutter Cane didn't actually write the events of the movie.]]
While John Trent goes off the deep end after discovering that he is a fictional character written by Sutter Cane, he is only half right, and the truth is far worse: Sutter Cane is also a fictional character, written by an EldritchAbomination to write the gateway into our world for its kind. This means that John Trent is a fiction written by a fiction, and his whole world is even ''less'' real than he thinks he's discovered.
* According to TheOtherWiki, Michael De Luca wrote it. Trent is the fictional being created by a fictional insane author who sold his soul and all of fictional reality to a fictional EldritchAbomination all because of Michael De Luca, who proved thoroughly that TheFourthWallWillNotProtectYou certainly swings both ways, if it [[NoFourthWall exists at all.]] I wonder if Trent is aware of the existence of SamNeill portraying/living out his life?
