Well, the official trailer is out for Harry Potter and the Deathly Hallows. It presents the two part presentation idea pretty well. It includes scenes which have to be from the second part, as well.
Part one is expected out this November, and part two in July, 2011.
It will be interesting to see where they ended up splitting up the two parts. There has been some discussion about this. Imdb.com has a break posted. Who knows what will be in the end.
Personally, I think the best place to break it up is after "Ron's return." That's all I'm going to say, so as not to ruin it for those of you who have not read the book.
The trailer looks good, but then so did the trailer for Harry Potter 6, and that film did not live up to its expectiations. Neither did the Harry Potter 5 film. OF course, that book was over 900 pages. it was crazy to try to jam it all into one film. It looks like they learned from this mistake by splitting up Harry Potter 7.
Some say that this is a ploy by author JK Rowling to drag out the franchise. So, what? It's still a good idea.
In the meantime, enjoy the trailer!
