Warner Bros. is expected to officially announce plans to release the final Harry Potter book as two separate films.
Considering the length of the final book (36 chapters/759 pages), you can’t fault the decision really.
Plans are for Warner Bros. to release Harry Potter and the Deathly Hallows: Part I in November 2010, followed by Harry Potter and the Deathly Hallows: Part II six months later in May 2011. Both films will be filmed concurrently.
Steve Kloves, who wrote five of the prior six films, is currently at work on both screenplays and director David Yates (who directed both ‘Order of the Phoenix’ and ‘Half-Blood Prince’) has already signed on for both sequels.
Producer David Heyman explained the decision to the LA Times:
“I swear to you it was born out of purely creative reasons. Unlike every other book, you cannot remove elements of this book. You can remove scenes of Ron playing quidditch from the fifth book, and you can remove Hermione and S.P.E.W. [Society for the Promotion of Elfish Welfare] and those subplots . . . but with the seventh, that can’t be done.” “The question will be, where do you break it? And how do you make them one but two separate and distinct stories? Do you break it with a moment of suspense or one of resolution? These are the interesting challenges. But each book has presented its challenges.”
