I guess there are a lot of similarities in different books, movies, and tv programs. As much as we try it's nearly impossible to think of something that hasn't been done in some way. Just look at all the vampire stuff that's out there now. Right around the time the Harry Potter books were coming out I was watching a movie on tv. I don't have any idea what it was about, except that it definitely had witches. The weird thing was the main character was named Harry Potter. I don't know when it was made, but I thought that was just a weird coincidence.
