It's up on the
official website.
It's a little over two minutes, but it's for both Part 1 and 2. If you look carefully you'll see Griphook, Draco, and Lucius! Although there's one part where Hermione is dressed kind of nicely with Harry trying to help a shirtless Ron in the background. I wonder which scene that is? Maybe they're just on the run from the wedding? And who's that trying to stop the Hogwart's Express?
I guess doing the teaser for the entire book would minimize the guesses of where they're going to cut off the film.
Maybe someone will be so nice as to make some icons?? Pretty please?
