What an excellent day for an exorcism.
The power of Christ compels you!
Your mothers in here with us, Karras.

Linda Blair in The Exorcist (1973) | IMDb
Would you like to leave a message?
Ill see that she gets it.
Its the power of the devil.

Hes in the girl.
Your mother sucks cocks in hell, Karras!
Do you know what she did?
Your c*nting daughter?
Im telling you that that thing upstairs isnt my daughter!
I cast you out!
Youre going to die up there.
There is only one.
So, if youre 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 doesnt say shes a demon.
She says shes the devil himself.
And if youve seen as many psychotics as I have, youd know its like saying youre Napoleon Bonaparte.
Father, could ya help an old altar boy?
Im not afraid of dying.
Im 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.
Youre a good boy.
The sow is mine!
Merrin, what is that?
You show me Regans double, same face, same voice, everything.
And Id know it wasnt Regan.
Ive never seen anything like this in all my life.
The girl is gone!
You killed your mother!
