I went to see the exorcist at the theater when it first came out in 1973. I was 11. I went with 2 teenagers. we had to cross a church picket line to get in the theater and they were pissed that I was so young. One of my friends pretended to be my older brother and almost had to fight our way in.
I was scared shitless before the movie even started. ...and then it was the scariest movie I'd ever seen.
