Theres a lot to unpack in The Exorcism, the new film from writer/director Joshua John Miller and co-writer M.A. Fortin, not the least of which is where the movie came from, and what its trying to achieve. For Miller, the son of the late actor Jason Miller (Father Damien Karras in The Exorcist), he says that in addition to being a love letter to his dad, its also a FU letter to Hollywood a little bit.
