Earlier today we /the-twilight-saga-breaking-dawn-adds-maggie-grace/learned that Maggie Grace has joined The Twilight Saga: Breaking Dawn to play Irina, and now Entertainment Weekly is reporting that 9-year old Mackenzie Foy is in negotiations 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.

A difficult task for Mackenzie Foy will be how to portray Renesmee, a 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 Mackenzie Foy's face would be digitally transferred onto the face of a younger child.
