Deadline is reporting that former Lostie and Taken chick, Maggie Grace, has signed on to the final two installments of the Twilight series: Breaking Dawn.  Melissa Rosenberg is scripting and Bill Condon is directing the two-part finale to the Stephenie Meyer vampire franchise, which will have release dates of November 18, 2011 and November 16, 2012 respectively…so you know which weekends to go camping or something.   Grace will be portraying Irina, a vampire in the Denali coven (who knew there was a vampire clan exclusive to the GMC Yukon XL?), which is a cousin troupe to the Cullen clan and are also “vegetarian” vampires.  Irina will blame the Cullen clan for the death of her lover and her actions set in motion a terrifying chain of events.

Grace has most recently appeared in Knight and Day and has just completed the Dwayne Johnson actioner, Faster.  She is currently filming the film, Lock Out, for directors James Mather and Stephen St. Leger.  She also has the upcoming Relative Insanity for director Larry Moss on her slate.
