Some actors take their acting careers to new heights. These actors went above and above for their roles, whether it was raising or reducing weight, utilizing prosthetics, or even changing genders. There were some who spent hours a day applying cosmetics to their skin, there were others who worked out for long periods of time, and then there were those who had serious injuries as a result of their efforts. This is a sampling of the performers that went to extreme lengths in order to get roles.

The actress gained weight, colored her hair, and shaved her eyebrows for the role
Charlize Theron’s portrayal of Aileen Wuornos as a serial killer is a great place to start. The Academy Award for Best Actress went to the South African actress for her portrayal in this role, after all. Charlize changed her hair color, shaved her brows, donned artificial teeth and contact lenses, gained weight, and used skin-discoloration cosmetics to play this persona.

Rather than gaining a large amount of weight, the actress’ goal was just to better embody her character’s demeanor. To go into the head of the infamous murderer, she decided to let go of her bodily self.
