Before The Exorcist terrified the world, its creator was writing comedy. In this episode, Adam traces how William Peter Blatty’s transformation – from humorist to theologian of horror – produced one of the most powerful and unsettling films ever made. From his early hoax as a “Saudi prince” on You Bet Your Life to the real 1949 exorcism that inspired his novel, this is the strange, very human story behind a movie that redefined good and evil on screen.

Key Takeaways
-
The Exorcist was conceived not as exploitation but as a theological argument disguised as horror, aiming to prove that if evil exists, so must good.
-
Many “cursed” events during production have rational explanations – but they fed a mythos that mirrored the film’s own themes of belief and doubt.
-
Blatty’s career forms a through-line from humor to hope, from laughter to loss. His horror was always about faith.
