    Please use the correct tags. If I'm not mistaken, you've been told to do so at least once already, and you have used inappropriate, vague tags like "books" and "movies" several times. If you're asking about LotR, use the "Lord-of-the-Rings" tag. If you're asking about Star Wars, use "Star-Wars". – Wad Cheber Jan 9 '16 at 18:51

    I've undeleted the question. It can still help people find the accepted answer to this sort of question by directing them to the first question. – AncientSwordRage Jan 9 '16 at 20:06
