Harry Potter and the Half-Blood Prince Trailer made by a fan. Watch and enjoy if you would like. You might want to use your imagination with the clips. ;) It would be nice if you commented too, so I know what you liked or didn’t like about it. The movie is being released November 2008. EDIT: People seem to be confused about the fan-made part of the movie. Yes, the sixth Harry Potter movie is not out, nor is it's trailer. Yes, these clips are from movies 1 through 4. You caught me, it's not the real trailer for the real Half-Blood Prince movie.
