I read the comment from die hard fans of Harry Potter and The Half Blood Prince from youtube.

"He is really angry at Warner Bros for releasing the only 23 second trailer"

So I updated the long version Harry Potter Half Blood Prince trailer for any hard fans for Harry Potter. Watch this really impressing trailer and enjoy.

The Harry Potter film's directors ,David Yates, said that films editing are complete and be ready for fully view for Harry Potter full movie from Warner Bros.
