Mark our words, 2014 will be Margot Robbie’s breakout year. The Wolf of Wall Street beauty has already left her mark on the public thanks to her uber-sexy role in the Oscar-nominated film, and her killer style on the red carpet this awards season. But that doesn’t mean the rising talent is shying away from taking risks. Case in point: she just made a dramatic change to her look for a new role!

Margot posted a photo to WhoSay yesterday from the set of her new film, Z for Zachariah, and we almost didn’t recognize her! The normally-blonde actress was makeup free (not like she needs it!) and has dyed her platinum locks a mousy brown hue — and she tops it all off with a grungy trucker hat. A bit of a departure from her glam Golden Globes appearance, right?

“First day on set for Z! She ain't a Duchess no more,” Margot captions the photo, referring to her character in Wolf of Wall Street’s nickname, “Duchess of Bay Ridge.”

A little over a week ago, it was announced that the Australian-born star would be replacing Amanda Seyfried as the lead in the indie film, and now she’s already down in New Zealand filming. Chris Pine and Oscar-nominee Chiwetel Ejiofor (12 Years a Slave) will also star in the post apocalyptic story of an American woman who seems to be the only survivor of a nuclear war — but all is not as it seems. Sounds like a promising project for such a promising talent!
