You know that movies telegraph their intent by mood music. Editing and the proper music can turn any movie into something completely different. Folks on the internet have made a cottage industry of changing an existing movie's genre with a little editing and a very different soundtrack. You can see five comedies, even family films, turned into horror movies with recuts at TVOM. Admit it, Willie Wonke and the Chocolate Factory would be a great horror film. But you haven't seen anything until you've seen the horror of Dumb and Dumber.
