Kristen Stewart & Robert Pattinson star as Bella and Edward in The Twilight Saga: Eclipse. Edward is a vampire who chooses not to feast on human blood. Instead, he drinks animal blood to survive, and because of this he and his family are known as vampire vegetarians. When Edward falls in love with Bella, a human, both of their worlds become very complicated. Edward is nervous when he gets too close to Bella, because he doesn't know if he can control his vampire instincts.
