The Exorcist (1973, Dir. William Friedkin)
Something beyond evil is happening in a little girl's room. Regan (Blair) has brutally changed both in the way she looks and the way she acts, with violent outbursts on everyone who comes in contact with her. Her worried mother (Burstyn) gets in contact with a priest (Miller) who comes to the conclusion that Regan is possessed. The top priest who can deal with an exorcism, Father Merrin (Sydow) is called in to help save Regan from the demon inside her.
Although the scare factor it once had has decreased since then, this freaky and bizarre horror uses all the successful horror conventions to make a successful horror film. The effects are brilliant and the acting is so realistic. This is a pure horror classic.
Mother? What's wrong with me?  Regan (Linda Blair)
It's just like the doctor said. It's nerves, and that's all. You just take your pills and you'll be fine, really. Okay?  Chris MacNeil (Ellen Burstyn)
