Snitchseeker recently posted this one their site:
The official theatrical release date for the first of two parts of the seventh and final chapter of the Harry Potter series, Deathly Hallows: Part I, has been announced: November 19, 2010.
The date for the second part of the seventh film, Deathly Hallows: Part II, has not been revealed yet, though Warner Bros. already stated that it will make its way into theatres summer 2011.
Sounds like a nice release date. First part to be set as a holiday film and the next one as a big blockbuster film. This is a good decision because of the two halves of the book and how it is set up. The first half of the book definitely more story-oriented, or in other words, a lot of talking, not much happening and not much action. The second half of the book, by contrast is very very action-packed, with the Malfoy Manor and Gringott's Robbery and of course the final battle at Hogwarts. The winter film, which will be set around other films that are much like it (more story-oriented) will suit itself more into the season while the summer film will be set around other large, action-packy films.
