Someone asked me what my favourite horror films were. I couldn't work out a top ten, but I think my top five favourite, in no particular order, are
The Shining - Stanley Kubrick
Henry: Portrait of a Serial Killer - John McNaughton
Halloween - John Carpenter
Psycho - Alfred Hitchcock
Dawn of the Dead - George A. Romero
Perhaps interestingly, only one of the above films -The Shining- features explicitly supernatural forces.
