Sienna Miller looked unrecognizable as she graced the Los Angeles set of Clint Eastwood's new flick, "American Sniper," on Tuesday, May 13.
Just like her co-star Bradley Cooper, who gained 40 pounds to play Navy SEAL Chris Kyle in the film (which is based on a true story), Miller changed her appearance drastically for her role as Kyle's wife Taya Renae Kyle. The 32-year-old actress debuted her new fiery red hair, which is a sudden change from her typically blond locks.
Miller reportedly beat out actresses Jaimie Alexander and Kate Mara for the coveted redheaded role.
