A few days ago, a bootlegged and blurry copy of the first Harry Potter and the Deathly Hallowsteaser went live before being predictably yanked by Warner Bros. But it didn't take long for the studio to release an official copy, complete with an introduction from producer David Heyman and director David Yates. While the teaser attempts to explain what the Deathly Hallows actually are, Harry Potter fans will be too busy scanning the footage for recognizable scenes. If you know what you're watching, there's quite a bit to see! I would nerdishly list all the moments but no one wants to read that, and it's more fun to let something like this unfold for each and every fan. You might choke up a little. I did. It's the last one!

For those unfamiliar with the final book you may wish for a little more context, but you'll undoubtedly be glad to see all the dark and gory images on display. Deathly Hallows is really the Potter story where the danger, the horror, and the despair really take over the story. Think of the end of The Empire Strikes Back and Frodo's march through Mordor in The Return of the King, and you have an idea of what a grim, unrelenting story this two-parter will be.

The trailer is embedded below the jump. Part one of Harry Potter and the Deathly Hallows hits theaters on November 19, 2010.
