"They're gonna love it, and Bill [Condon, the director] even told me that, stay for the credits -- there's a really special thing happening," he told The Insider.
He also added that Condon changed the ending of the original book, written by Stephenie Meyer. "Every film's been building and building, and Bill Condon really had a great idea with ending the series with 'Breaking Dawn 2,' and just adding a little more flavor to parts of the book that weren't there, but he elaborated more on. I think the fans are really going to enjoy it."
