To top last week’s news on the stills for Harry Potter and the Deathly Hallows, a teaser for the movie has leaked online after appearing as a special feature on the Blu-Ray edition for Harry Potter and the Half-Blood Prince.  The preview begins with behind-the-scenes footage and interviews with producer David Heyman and director David Yates.

Like the book, the teaser displays a darker tone for the remainder of the series.  And watch closely for footage of John Hurt returning as Mr. Ollivander.
