The Exorcist is up there as one of my favourites. My Gran had some sort of bootleg VHS that came from the states, and she never let me watch it, despite letting me see all sorts of other horror films. I was about 12 when she and my Grandad went to a wedding and my cousins were looking after me and we watched it and scared the hell out of ourselves. I didn't see it again until "The Version You've Never Seen" was released and I saw it in the cinema. There was a stage production of it toured a few years back as well. That was astounding. Can't wait for the new one.
