Today EW Hollywood Insider broke the news that Renesmee will be played by newcomer Mackenzie Foy. Foy is nine years old, so there will either be some serious CGI used for a younger Renesmee or they will be casting younger actors for what leads up to the “older” Renesmee.
Maggie Grace (Lost, Taken) also landed the part of vampire Irina, who is a member of the other “vegetarian” vampire clan, The Denalis. Irina is also a vengeful lover after her partner Laurent is killed in Forks. Trust me, the way Irina gets back at the Cullens is way more climatic than what happened with Victoria.
It should also be noted that Rami Malek (The Pacific) was cast as vampire Benjamin (from an Egyptian clan and can control natural elements) a few weeks ago.
All three of these new cast members may not be seen until The Twilight Saga: Breaking Dawn Part 2 which is due in theatres November 16, 2012.
It should also be noted that November 17, 2012 is when I finally get my life back and my twitter following number will drop significantly.
