Japanese Trailer: Harry Potter and the Half Blood Prince

I came across a new trailer for 'Harry Potter and the Half Blood Prince' with some pretty cool new footage that we have not seen yet. One top of that we have a Japanese voice over thing going on during the trailer, but the footage is in English. I'm not sure why all of the overseas countries get the better trailers with better footage but that's just the way it is. These harry Potter films just keep getting better and better, and I am pretty excited to watch this one. Having not read the books there are no expectations to be ruined for me. The trailer is introduced by Daniel Radcliffe. Check it out below!
