Now this is a dark trailer! Seeing that many of 2009’s tentpoles are throwing up new trailers this week and next. Warner Brothers clearly felt it wouldn’t be wise to leave out Harry Potter & The Half Blood Prince.

Completely unannounced and very unexpected this third trailer is now available here. I think upon watching it you would agree it is by far the best we have seen so far capturing every element that made the last installment, by director David Yates, a success with buckets load to spare…roll on next July!
