It will be cool to have a HP short film festival where many can direct a short film based on the movies we've watched or the books we've read. For instance if u feel that u can make any part of the movie, in the aspect that u want to add a part of the context from the book that the movie didn't contain then make the film in your point of view. As we know there are things in the book that the movie does not provide and that can disappoint us, so a gr8t example would be HP the 5th part where they actually describe more the relationship between Harry and Cho (which is pretty funny actually). All it is, is having fun making a film by searching for charater look alikes or just simply sharing ur creation in imagination.
