Extended Trailer for Half-Blood Prince Screened Today at ShoWestHBP Film
Multiple reports are online this hour stating an extended trailer for Harry Potter and the Half-Blood Prince was screened today at the ShoWest convention. Slashfilm.com states that Before presenting the trailer for Harry Potter and the Half Blood Prince,
Warner Bros head Alan Horn joked that he hopes fans can forgive him for
moving the film to July, and that “we got a few emails about that one.”
Cinemablend also has a longer article on the trailer. Most of what was described seems to be what we saw in the recently released trailer at the beginning of the month, with the footage of the attack on the Burrow, and the Inferi, however it does seem there was at least one new, and rather plot revealing, piece of dialogue, as they state "Dumbledore also has a line of dialogue that definitely isn't part of the book-- "Voldemort has chosen Draco Malfoy for a mission."
Also the article says that we may perhaps will see more on the Katie Bell and the cursed necklace scene. More when we get it, stay tuned!
