I was wondering if there are any other good extended universes to get hooked on. I know Star Trek has an extended universe outside the movies and TV show, but I'm not into that. My friend who is in Lord of the Rings told me that had an extended universe to it outside the movies, but I can't find information on it. I was wondering if there were other good trilogies or good movie series that have a good extended universe to it. I am glad you were able to find a few suggestions here, but since this is a forum for fan fiction, and this is not, I am going to have to lock this thread now.
