The Final Harry Potter And The Half-Blood Prince Movie Trailer

Warner Bros has officially released the third and likely final trailer for Harry Potter and the Half-Blood Prince. You may have noticed that a low res version of the trailer leaked earlier today thanks to E! Online. But now the higher resolution trailer is now available, as well as HD viewing options. I've said it before, and I'll say it again... is it just me or is every new trailer more epic than the last? Watch the trailer embedded after the jump and leave your thoughts in the comments below.

Voldemort is tightening his grip on both the Muggle and wizarding worlds and Hogwarts is no longer the safe haven it once was. Harry suspects that dangers may even lie within the castle, but Dumbledore is more intent upon preparing him for the final battle that he knows is fast approaching. Together they work to find the key to unlock Voldemort's defenses and, to this end, Dumbledore recruits his old friend and colleague, the well-connected and unsuspecting bon vivant Professor Horace Slughorn, whom he believes holds crucial information. Meanwhile, the students are under attack from a very different adversary as teenage hormones rage across the ramparts. Harry finds himself more and more drawn to Ginny, but so is Dean Thomas. And Lavender Brown has decided that Ron is the one for her, only she hadn't counted on Romilda Vane's chocolates! And then there's Hermione, simmering with jealousy but determined not to show her feelings. As romance blossoms, one student remains aloof. He is determined to make his mark, albeit a dark one. Love is in the air, but tragedy lies ahead and Hogwarts may never be the same again.
