How breakout star Margot Robbie of 'Suicide Squad' and 'Wolf of Wall Street' is taking over Hollywood

Warner Bros.

Margot Robbie left jaws on the floor after her breakout performance opposite Leonardo DiCaprio in "The Wolf of Wall Street."

Now the Aussie actress, 25, is taking a central role in the upcoming "Suicide Squad" movie as the comic-book character Harley Quinn.

The newest trailer dropped this week and it looks like Harley's origin story will take up a large chunk of screen time — and Robbie has a delightfully unhinged presence.

Robbie also has two other films coming out this year: a live-action Tarzan remake, "The Legend of Tarzan," and comedy "Whisky Tango Foxtrot." 

In honor of Robbie's newfound success, we're looking back at how she became a Hollywood star.

Born in 1990, Margot Robbie grew up on her grandparents' farm on Australia's Gold Coast. A business-savvy child, she would make up magic tricks and put on shows, charging anyone who wanted to learn her tricks.

She bought her first surfboard at a garage sale when she was 10. "I'm happiest when I'm surfing or out on the farm hunting wild pigs ... or riding around on motorbikes," she said in a 2008 interview.

As a teen, she worked as a subway artist at a Subway in Melbourne. (Six months after Robbie landed her first major acting role, Subway hired her for a commercial. "I got paid like 20 times the amount I ever earned there," Robbie says.)
