You won't find a more iconic film—The Exorcist. And that's for good reason. After all, this was a film heralded as an Oscar winner for Best Adapted Screenplay, Best Sound Mixing, and a few Golden Globes to boot. Which of those Globes did the movie win? Try Best Motion Picture, Best Supporting Actress, Best Screenplay, and Best Director.
When you think about it, out of all sub-genres and tropes in horror media, quite honestly the concept of demonic possession envelopes and chokes the fear into and out of many simply out of enigma. And it's not even limited to Christianity.
Seriously? Don't mean to poke fun at this, but it really is true: somehow, some way, it seems that in the classic trope and style of a horror film from the bowels of B-cheese like Friday the 13th to even the most modern found footage flicks of The Blair Witch Project, the fact is forests freak people out.
And you thought that it was an M. Night Shyamalan affair, right? Wrong.
