Celebrities Who Went on Diets For Movie Role

Emily has dropped weight not once, but twice for movie roles. Like Natalie and Mila in Black Swan, Emily followed a rigorous fitness routine to get her body in professional-dancer shape for The Adjustment Bureau, training for almost four hours each day in the month that led up to filming.

Playing the role of Emily in The Devil Wears Prada was a bit different because the character is "on the edge of anorexia." Emily told LA Times Magazine she was encouraged by those involved in the film to lose weight since her character "literally did not eat."
