United Press International has an article that states that crew members working on the current movie adaptation of the 6th book, Harry Potter and The Half-Blood Prince, has mentioned that the 7th book might have to be made into two movies. Their concern is that there is so much story in the final book, Harry Potter and The Deathly Hollows, that it would be difficult to reduce it into a single movie.
"There's so much to fit that the view is the last movie should be in two halves," one anonymous source said. "There is a huge battle when Harry, played by Daniel Radcliffe, takes on Voldemort that needs to be done really well."
They state that it is all a matter of keeping the "artistic vision" of the story intact and it is "not aimed at cashing in on the highly profitable series." Which I frankly don't believe. I am an avid reader of the series and have watched the movies with cringes and cries of pain. They have manipulated, cut, and re-imagined the "artistic vision" of the previous books since the second movie. They have shown no concern for the original vision of the story nor presenting information that is vital to the depth of the story.
Simply put, they are just using the excuse of the battle at the end of the last book to milk this movie franchise for every penny they can get. It's no different then how many movies have repeated re-releases of movies in order to have people who love the movies buy them again for an added scene or feature. The scary thing is that despite so many of the buyers being aware of this fact, they still purchase the extended special editions and I have no doubt that people will watch the split-up Harry Potter movie.
Damn us all for being consumer whores.
