Maggie Grace will play a new vampire threat to Kristen Stewart's Bella in The Twilight Saga: Breaking Dawn. Grace, who played Liam Neeson's in-distress daughter in Taken, will play the role of Irina in the final installments of the Stephenie Meyer novel, which director Bill Condon is directing in two separate films.
9-year old Mackenzie Foy is inches away from signing on to play Renesmee, Edward and Bella’s vampire/human love child that’s a central role in the final installment of The Twilight Saga: Breaking Dawn.
It’s not yet clear how the diminutive actress, who’s appeared in one episode each of television shows FlashForward and ‘Til Death, will portray the character who ages a full 17 years in only seven. Sources have suggested that director Bill Condon will employ similar digital effects to those used by David Fincher in The Curious Case of Benjamin Button, where Foy’s face would be digitally transferred onto the face of a younger child. It’s also probable that the studio will hire a younger child in some capacity, too.
