Nicole Kidman is embracing her dark side!

The Oscar winner revealed a new brunette hair color while shooting Strangerland in Sydney on April 1. Clad in a chambray button-down shirt, Kidman wore her brown hair in a messy ponytail for filming. (She plays one-half of a couple whose teenage children go missing in the desert.)

"I am always looking for the right script to bring me home to Australia," the Sydney-raised actress, 46, told The Hollywood Reporter in March. "The moment I read Strangerland I knew this was a film I couldn't say no to. I'm looking forward to working on a film in Australia, and I'm very excited to be working with Joseph Fiennes and Hugo Weaving."

This isn't the first time the natural redhead has dyed her locks for a film role. In her new film The Railway Man (out April 11), the Oscar winner sports a brunette bob with bangs.
