Margot Robbie got her Hollywood break at age 23, playing Leonardo DiCaprio's wife in The Wolf of Wall Street, and you may have caught her in the short-lived Pan-Am before that. Since then, Margot's become a superstar playing American characters; she was even nominated for an Oscar for I, Tonya. But before all of that, she was famous in her native Australia (and indeed in the UK) for her role as Donna in Neighbours.
