Another cast has been added to the Twilight Saga: Breaking Dawn movie and that would be Maggie Grace as Irina. Maggie Grace will play as an antagonist in the movie.
To give you a brief description about the Irina’s character, well, she’s a vegetarian vampire from Denali coven and is considered cousins to the Cullen clan. Just like her sister, Irina loved all men and even humans.
Right before she was killed by Caius, after delivering a fake info to the Volturi about Renesmee, she was in relation with Laurent.
