New Moon the Movie: differs from the book?

Just read that there definitely will be at least a few detours from the book in New Moon the movie. So far, it's nothing to ruffle your feathers over. So, settle down Twilighters.

Life & Style magazine states that in New Moon, when Bella plays the dare devil to conjure up the sweet voice of beloved Edward, the actual image of Edward will appear. This of course allows for more Edward screen time. Which apparently Summit and Chris Weitz believe is the key to continued success in the movie adaptation of the saga. Maybe it's just me, but I would enjoy the movie even if Edward was a 'no show' for the whole middle of the movie. Not that I won't LOVE seeing him in phantom-ish visions throughout. But just like in the book, we all anguished over his absence, and it made his return all the sweeter.

Whatever though. Either way I'm stoked to see it.
