For her role as the iconic Winnie Mandela in the 2011 biopic, Jennifer Hudson lost a lot of weight. In fact, she lost so much that the director asked her to gain a few pounds!
Hudson started an extreme diet with Weight Watchers and nailed a nearly perfect South African accent. All in all, this former American idol singer was totally unrecognizable on screen.
Emma Stone
To become the legendary tennis player, Billie Jean King, in ‘Battle of the Sexes’, the red-headed beauty Emma Stone had to actually look like an athlete. This meant gaining 15 pounds, which meant limiting her diet to fattening protein shakes.
Stone, who we’re used to seeing as a stunning green-eyed redhead, turned into a buff athlete whose last concern was her looks. She delivered a stellar performance, and thankfully went back to her gorgeous self after the film ended.
Judy Greer
Judy Greer is a phenomenal actress, not to mention hysterically funny. When she played the ugly, ditsy Kitty Sanchez on 'Arrested Development', you would never have guessed that she's a beautiful red-head in real life.
Judy had this to say about the role, "I looked kind of weird for a long time. It was easier to be the funny friend instead of the pretty friend. I just didn't have the curves that most girls have, until very late, and I have really frizzy hair, and I had braces. I took ballet dancing forever and there was a natural transition into acting."
Lea Michele
Lea Michele's role as Rachel, on the popular TV show 'Glee', was not exactly known for her popularity or great sense of fashion. But in real life, Lea Michele is slim, stylish and very interested in health and wellness.
This just goes to show the actress's talent, which included a beautiful voice on the show too.
Jessica Biel
Jessica Biel is absolutely gorgeous. Since her film debut in 1997’s ‘Ulee’s Gold’, Biel has acted in several TV shows and movies, and she usually looks stunning in all of them. But in the 2012 thriller ‘Tall Man’, Biel transformed into someone else.
Playing a suburban nurse that’s desperately trying to save her son from an ominous abductor, Biel wears no makeup throughout the film, and the little she wears is to make her look exhausted, pale and gritty.
