Saying it's necessary to stay true to the book--and not at all related to the franchise's cash cow status--Warner Bros. says the final Harry Potter movie will actually be two movies. Warner Bros. President Jeff Robinov tells the Wall Street Journal that Harry Potter and the Deathly Hallows is "packed with vital plot points" and that "the best way to do the book, and its many fans, justice is to expand the screen adaptation." David Yates, who directed last summer's Harry Potter and the Order of the Phoenix and currently helming Half-Blood Prince will direct both Deathly Hallows films. Part one will open during the holiday season of 2010, with part two to be released the following summer. The first five films in the series have grossed $4.5 billion globally.
