Emma Stone looks almost unrecognisable for her new role

We had to do a double take.

Sometimes a red head and more recently a blonde.. we weren't expecting to see Emma stone with black hair for her new role. Playing Billie Jean King, a tennis star in Battle of the Sexes which premieres this month, you would hardly know the actress. The film which is based on a true story, follows tennis star King circa 1973, when she faced Bobby Riggs in the most famous "exhibition tennis match" to earn the title of "Battle of the Sexes." Riggs (Steve Carell in the movie) challenges King to a match, offering $100,000 as the cash prize. Their match, which aired September 20, 1973 on ABC, was viewed by over 90 million people worldwide. For the role, Stone underwent extensive training to have the same physical shape as King. As part of her training, she would workout twice a day — by the end of her training, she could deadlift 185 pounds. She told Entertainment Weekly that during this time she became "kind of a meathead." We cannot wait to see this film. Check out the trailer for yourself, the transformation is uncanny.   And look at Stone here with the real Billie Jean King! Aww!
