Charlize Theron (Monster)
Not only did Theron gain 30 pounds to play Wuornos (who Theron says wasn’t fat at all), but the actress addressed Wuornos’ actual lifestyle when it came to her physical appearance.
Writer-director Patty Jenkins said, “It was, ‘Oh, she was homeless. She lived on the street in bad weather. OK, well that means sun damage.’ Well, then we addressed the sun damage. She was insecure about her hair, OK, well, then we address the hair.”
