A new, and most likely final, Harry Potter and the Half-Blood Prince trailer is online, and it’s action-packed stuff. It also, rather impressively, manages to pull off the difficult trick of giving very little away while containing quite a few moments from the film’s third act, so those familiar with the book will have lots of fun combing through it to find those moments. Check it out in high def here.

The film’s out on July 15, two days earlier than the July 17 date that had been planned. Of course, it’s all still months later than the November 2008 release we were originally planning for, but look at it this way, Potter-heads: at least now there’s a shorter time between doses, with this film and Deathly Hallows: Part One a mere year-and-a-bit apart.
