Star Kellan Lutz has revealed that director Bill Condon changed the conclusion of Stephenie Meyer's final novel in the series to add "a little more flavour".
He also said that there is a post-credits scene that fans should stick around for.
"They're gonna love it, and Bill even told me that, stay for the credits - there's a really special thing happening," he told The Insider.
"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 flavour to parts of the book that weren't there, but he elaborated more on," he continued. "I think the fans are really going to enjoy it."
Lutz will reprise his role as vampire Emmett Cullen in the final chapter of The Twilight Saga.
The Twilight Saga: Breaking Dawn - Part 2 is due for release on November 16.
