The Exorcist is the film that put the horror subgenre on the map. There are dozens of imitators, but none have managed to scare up the fear factor and box office success of the 1973 film. Besides killing it in the pop culture world in terms of its resonance, the film has produced its share of terrifying (and also funny) lines. Here are some of the best The Exorcist quotes.

Demon: What an excellent day for an exorcism.
Father Damien Karras: You would like that?
Demon: Intensely.
Father Damien Karras: But wouldn't that drive you out of Regan?
Demon: It would bring us together.
Father Damien Karras: You and Regan?
Demon: You and us. | permalink

Demon: Your mother sucks (expletive) in Hell, Karras, you faithless slime. | permalink

Father Merrin: Especially important is the warning to avoid conversations with the demon. We may ask what is relevant but anything beyond that is dangerous. 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. So don't listen to him. Remember that -- do not listen. | permalink

Psychiatrist: Is it Captain Howdy?
Regan MacNeil: I don't know.
Psychiatrist: If I ask him to tell me, will you let him answer?

Psychiatrist: Why not?

Demon: (Expletive) him!
