Trailer: Harry Potter Takes a Turn for the Dark with the Half-Blood Prince

Not strictly horror, I know, but don't you just love it when an established entertainment property dabbles in more sinister territory? The Harry Potter series started out as safe family fare, but this brand-new trailer for the sixth film in the series, Harry Potter and the Half-Blood Prince, shows us a much more horrifying side of the mythos. Decidedly grown-up in tone, it focuses on the young Voldemort (as played by Ralph Fiennes' nephew Hero Fiennes-Tiffin), before he became J.K. Rowling's personification of evil. And I'll be damned if that last shot isn't a tip of the hat to The Exorcist...
