In The Twilight Saga: Breaking Dawn – Part 2, in theaters November 16, Bella Swan (Kristen Stewart) must learn to control her urges as a bloodthirsty vampire while becoming a protective mother to daughter Renesmee (played by 11-year-old Mackenzie Foy) with sparkly vamp dad Edward Cullen (Robert Pattinson).
