Since there are like 90878976 threads about movies doing the rounds, I figured I'd add this one to the mix .
For me, it's hands down The Exorcist. I've seen it twice, once when I was 8 (yeah, thanks mum) and once when I was 18. Absolutely horrified me each time and even thinking about it gives me chills. It's weird as I think most people see that film as a comedy these days!!
So what's the scariest movie you've seen?
