The Exorcist (franchise)
The Exorcist is an American horror media franchise that originated with William Peter Blatty's 1971 horror novel (itself inspired by the 1949 exorcism of Roland Doe) and most prominently featured in a 1973 film adaptation of the novel, spawned many subsequent prequels and sequels although none of them (excluding the television series) compared positively to the original.
