Amazing body transformation for roles in Hollywood

This drop-dead gorgeous actress Charlize Theron knew she had to take a risk if she wanted to 'kill it' in Hollywood. But playing serial killer Aileen Wuornos in 2003's Monster was certainly anything but glamorous. She gained 30 pounds, mostly by eating donuts and potato chips. She also wore fake teeth and makeup to give her skin a splotchy appearance. Theron was rewarded with an Academy Award for Best Actress in a Leading Role.
