According to Wikipedia in August of 2011, Le Manoir du diable by Georges Melies is the first horror movie. Well, actually its a short film (about three minuets or so) but film was really hard to come by in that time so this counts as a film to me. The plot of the film is basic, you have your hero being tormented by demonic things in a crazy castle room... However, that plot isn't what brought the crowds. The thing that drove the popularity of these films was the fact that you were seeing motion on screen. I suggest going and seeing Hugo. That film is spectacular. It answered so many question...
