WOW!!! OMG!!! I absolutely loved it. First, I opened snitchseeker and then when I saw this, I just stared at the words "Deathly Hallows" and "Trailer" with my mouth hanging open. Then I recovered from Paralyzation and started screaming. Now my mom thinks I'm seriously crazy.

Anyways, I like the fact that they decided to just keep the characters as the original actors for the graveyard scene, since Hermoine and Harry were supposed to look like muggles and the emotions would not have been as strong if the audience watched a random person crying over Harry's grave, where as if it is Harry in person, then it would look much better.
While watching this teaser trailer, I thought I was having flashbacks of when I read the book 'cause it looked so similar to how I imagined some scenes.
