The Exorcist (1973, dir. William Friedkin)
The grandaddy of all the horror movies on my list. The one that I’ve seen the least amount of times because of it’s power. The Exorcist centers on a young girl who becomes possessed by a demon and the priests who try to free her from its grasp.
A lot of the horror in this one comes from the interactions between the priests and the young girl, mostly from the vile things she says to terrify them. I don’t think it helps that as the possession goes on, her face changes as if it’s rotting.
I should say I’m talking specifically about the theatrical cut. The version that came out later added a fucked up scene where she comes down the stairs with her body contorted in what was called the spider walk, fuck that version.
