This is not really a teaser trailer, but it does contain some footage from the film, and some behind the scenes footage too. This is a very short featurette that on the end contains a very short, special effects free, clipped together teaser with John Hurt narrating a very dark series of clips.

I love the two scenes back to back of Harry Potter lying down in distress and then Hermione holding her blood covered hands to the camera. Ooooh, this is going to be dark.

You can see the featurette right here through First Showing who were the first to catch it online it would seem.

Apart from the teaser on the end there are some nice behind the scenes shots and we hear from the director and producer, but it is short, so you might want to watch it a couple of times.

Excited for Harry Potter and the Deathly Hallows: Part I yet? I certainly am because it looks much darker than the rest, and not being a fan of the books I'm not sold into all the pre-hype about it either. In my mind Harry Potter is still a pretty mediocre magician as things go and I'd like to see him develop in that area, after all he's supposed to be up against the creature who can defeat the best magicians in his world.
