1. The Four Renesmees
According to Celebuzz, there will be four Renesmees in Breaking Dawn to help with the super fast ageing process of Edward and Bella’s daughter. Mackenzie Foy will be the main Renesmee, but as the character ages her head will be digitally superimposed onto the bodies of other girls. The other girls known are Eliza Faria, Rachel St. Gelais and Sierra Pitkin. To view photos of the four girls, there's a slideshow on the bottom. The first picture of the girl in the meadow is Mackenzie.
2. Edward plays Renesmee's Lullaby
Ever since the announcement that Carter Burwell (Twilight’s score composer) would be returning to The Twilight Saga: Breaking Dawn, Twilight fans have been wondering whether that means Robert Pattinson (“Edward Cullen”) would be playing “Bella’s Lullaby” once again in the film (as is done in the book). According to a post on Carter Burwell's homepage, the answer is yes. And he just wrote “Renesmee’s Lullaby” for Twilight Breaking Dawn 2, which Rob Pattinson will play on camera. The film will be released in November 2012.
