The buzz is building for New Moon.
Filming has started on Eclipse.
But what about Breaking Down? The fourth book in Stephenie Meyer's series is coming to theaters, right?
"The fans should rest assured the we're working with Stephenie Meyer to bring Breaking Dawn to the big screen," a rep told E! News. "As in all creative processes, things take time. We want to make sure we get it right."
Because the final film in the franchise is more adult than any other, those behind it are worried about toning down its scenes.
"Our fans are in the PG age range, and I don't feel a big necessity to see violence and to see gore," said Melissa Rosenberg, a writer in Twilight, New Moon and Eclipse.
As for the movie's stars, Kristen Stewart said earlier this year that she certainly assumes Breaking Dawn will be made.
"We all really hope there is going to be a number four. I'm pretty confident that the fans aren't going to... lose interest. The only case that a fourth one wouldn't be made is if all of a sudden people stopped caring, and I really don't think that's going to happen."
