If you were one of the tens of people who watched The Vampire Diaries this past week, you got a little treat -- the debut of the first TV spot for the first installment of Harry Potter and the Deathly Hallows. Each new peek at additional footage from the penultimate Potter flick gives us something new to coo over: Hagrid dueling with the Death Eaters in the sky! The destruction of the Burrow! Ghost Dumbledore! The exciting trailer after the jump.
