Monster is a biographical film about serial killer Aileen Wuornos, who was eventually put to death in the state of Florida. Monster took a look at the life of Wuornos, starting before she began her killing spree until her capture by police. Wuornos suffered from mental illness, beginning when she was a child suffering horrific abuse at the hands of her male family members.

To play the part of Wuornos, who was despised far more than any male serial killer, Theron—known for her dedication and willingness to dive into a role—had to gain thirty pounds, shave her eyebrows, and wear prosthetic teeth. She received an Oscar for her stunning transformation and jarring performance.
