The Exorcist, which premiered on December 26, 1973, remains one of the most influential and memorable horror movies of all time. Based on the novel of the same name by William Friedkin, the story brought a new level of graphic depiction to the supernatural horror subgenre. Exploring themes of good vs. evil and the role of faith in the household (and community), The Exorcist influenced the likes of Rosemary’s Baby, The Omen, and more recent films like The Conjuring. Nominated for multiple Academy Awards, the film premiered to critical and commercial success. So, on the 50th anniversary of the triumphant horror staple, let’s look back on some of the most memorable quotes from the movie — that have weaved their way into the cultural fabric of the horror-loving community. 

“What an excellent day for an exorcism.”

“The power of Christ compels you!”

“Your mother’s in here with us, Karras. Would you like to leave a message? I’ll see that she gets it.”

“It’s the power of the devil. He’s in the girl.”

“Your mother sucks cocks in hell, Karras!”

“Do you know what she did? Your c*nting daughter?”

“I’m telling you that that thing upstairs isn’t my daughter!”

“I’m not Regan.”

“I cast you out! Unclean spirit!”

“You’re going to die up there.”

“There is only one.”

“You’re a scientist.”

“So, if you’re the devil, why not make the straps disappear?”

“What happened to your manners?”

“There are no experts. You probably know as much about possession as most priests. Look, your daughter doesn’t say she’s a demon. She says she’s the devil himself. And if you’ve seen as many psychotics as I have, you’d know it’s like saying you’re Napoleon Bonaparte.” 

“Father, could ya help an old altar boy?”

“I’m not afraid of dying. I’m afraid of being alone.”

“He is a liar. The demon is a liar. He will lie to confuse us. But he will also mix lies with the truth to attack us. The attack is psychological, Damien, and powerful.”

“You’re a good boy. I love you.”

“Keep away! The sow is mine!”

“Merrin, what is that?”

“You show me Regan’s double, same face, same voice, everything. And I’d know it wasn’t Regan.”

“I’ve never seen anything like this in all my life.”

“The girl is gone!”

“You killed your mother!”
